# Given a spinner with 9 equal-area sections, a trial of 100 spins resulted in an experimental probability of 13% for the spinner landing on 4. which of the following statements must be false? a. the theoretical probability p(spinner < 4) = 100% b. the theoretical probability p(spinner =4) = 11% c. in a new trial of 100 spins, the experimental probability, p(spinner=4) may be different. d. the experimental probability p(not spinner =4) = 87% for this trial. jaygamer37

The probability of the spinner landing on A is 0.1111.

Step-by-step explanation:

The possible outcomes of a board game is that it can lead on any three of the regions, A, B and C.

The probability of all the outcomes of an event sums up to be 1. According to the provided information:

P (B) = 3 P (A)

P (C) = 5 P (A)

Compute the probability of the spinner landing on A as follows: Thus, the probability of the spinner landing on A is 0.1111. nikejose11

Explanation:

I chose 1/8 because there were 8 numbers and 1 five. If there were 3 numbers and 1 five, the answer would be 1/3. andrejr0330jr

probability = 5/10 = 1/2 kingjames82

56

Step-by-step explanation:

P(red & red) = 0.5×0.6 = 0.3

P(blue & blue) = 0.5 × 0.4 = 0.2

84 = N(0.3)

N = 280

Expected no. of both blue:

280 × 0.2 = 56 joannakawata6

56 times

Step-by-step explanation:

To find the probability of both spinners landing on red, we need to multiply the probability of the spinner A landing on red (0.5) by the probability of the spinner B landing on red (0.6):

P(redA and redB) = 0.5 * 0.6 = 0.3

Then, to find the probability of both landing on blue, we do the same:

P(blueA and blueB) = 0.5 * 0.4 = 0.2

Now, if the number of times that both spinners land on red is 84, to estimate the number of times that both land blue, we just need to multiply this number of times by the ratio of P(blueA and blueB) over P(redA and redB):

84 * 0.2 / 0.3 = 56 times jason2351

52

Step-by-step explanation:

Spinner A

Probability of red = 0.5, Probability of blue = 0.5

Spinner B

Probability of red = 0.6, Probability of blue = 0.4

Probability of both A and B land on red:

0.5*0.6= 0.3

Number of attempts to get outcome of 84 red on both spinners is:

84/0.3= 260

Probability of both spinners land on blue:

0.5*0.4= 0.2

Estimated number of both spinners land on blue:

260*0.2= 52 BeautyxQueen

0.5

1/9

Step-by-step explanation:

Let's call x the probability of landing in A

So, probability of landing on B is 5x and probability of landing on C is 3x.

As we only have this options, the probabilities A + B + C = 1. So,

x + 5x + 3x = 1

9x = 1

x = 1/9 noahdeem135
