An urn contains 5 white and 10 black balls. A fair die is rolled and that number of balls is randomly chosen from the urn. What is the probability that all of the balls selected are white? What is the conditional probability that the die landed on 3 if all the balls selected are white?

Part A:

The probability that all of the balls selected are white:

Part B:

The conditional probability that the die landed on 3 if all the balls selected are white:

Step-by-step explanation:

A is the event all balls are white.

D_i is the dice outcome.

Sine the die is fair:

for i∈{1,2,3,4,5,6}

In case of 10 black and 5 white balls:

Part A:

The probability that all of the balls selected are white:

Part B:

The conditional probability that the die landed on 3 if all the balls selected are white:

We have to find

The data required is calculated above:

s + (a + 178) = 2000

step-by-step explanation:

2000 - 178 = 1822

1822 / 2 = 911

911 + 178 = 1089

1089 + 911 = 2000

abha = 1089

shane = 911

13

step-by-step explanation:

divide the cost of the total of sodas you bought by the cost of one soda, for example:

$24.57 divided by $1.89 is 13 which means you bought 13 sodas
