B and D

Step-by-step explanation:

B and D

yee yee

d b and d

Step-by-step explanation: on edge plz give 5 stars plz

B and D are independent.

Step-by-step explanation:

Events A and B are  independent when P(A\cap B)=P(A)\cdot P(B)

Here,

A is the event that the burrito is a chicken burrito

B is the event that the burrito is a carne asada burrito

C is the event that the customer requested black beans

D is the event that the customer requested pinto beans

P(A)=\dfrac{83}{240},\ P(B)=\dfrac{80}{240}=\dfrac{1}{3},\ P(C)=\dfrac{45}{240}=\dfrac{3}{16},\ P(D)=\dfrac{72}{240}=\dfrac{3}{10}

and

P(A\cap C)=\dfrac{37}{240},\ P(A\cap D)=\dfrac{30}{240},\ P(B\cap C)=\dfrac{5}{240},\ P(B\cap D)=\dfrac{24}{240}=\dfrac{1}{10}

Also,

P(A)\cdot P(C)=\dfrac{83}{1280},\ P(A)\cdot P(D)=\dfrac{83}{800},\ P(B)\cdot P(C)=\dfrac{1}{16},\ P(B)\cdot P(D)=\dfrac{1}{10}

As only P(B\cap D)=P(B)\cdot P(D), so B and D are independent.
