Question

A coin is flipped, then a standard number cube is rolled. Let A represent the event “the coin lands showing heads” and B represent “the standard number cube lands showing 4.”
What is P(A|B)? Convert answers to decimals and round to three decimal places when necessary.

Answer 1

Answer:

1/2

Step-by-step explanation:

Conditional probability, giving the standard number cube lands showing 4, think about what are all the possible sets left?

That's right, (Heads, 4) and (Tails,4)

Given that there are only 2 possible cases remaining, to get heads on the coins, there is only 1 possible case out of the two cases shown. P(A|B) is thus 1/2
