Aclass has 15 boys and 16 girls. what is the probability that a boy's name is drawn at random?

15 over 31
16 over 31
15 over 16
16 over 15

Answers

The answer is \frac{15}{31}

Step-by-step explanation:

In order to determine the probability, we have to know the classical probability.

Classical probability is a simple form of probability that has equal odds of something happening. The probability of a simple event happening is the number of times the event can happen, divided by the number of possible events.

Given:

A=amount of favorable outcomes

B=amount of possible outcomes

E=event

P(E)=\frac{A}{B}

So that, we have to determine:

the amount of possible outcomes:

B=15 boys + 16 girls =31

the amount of favorable outcomes:

A=15 boys

E= boy's name is drawn at random event

P(E)=\frac{15}{31}

Finally, the answer is \frac{15}{31}


Aclass has 15 boys and 16 girls. what is the probability that a boy's name is drawn at random?  15/3

15/31

Step-by-step explanation: because there are 31 kids in all and 15 of them are boys so 15/31

1. certain

2.15/31

3.40%

4.unlikely

A. 15 over 31

I took a the test and got it right, thank you!

15/31 because all together there would be 31 names to be drawn and there are 15 boys so therefore there would be 15/31 chance it would be a boy
15 over 31 is the answer.
15 boys and 16 girlstotal is (15 + 16) = 31

probability that a boys name is drawn : boys/total ppl = 15/31

15 over 31

Step-by-step explanation:

When dealing with problems like this, it is always going to be the number they are looking for over the total number.

15 over 31
