Question

suppose you spin the spinner below 5 times. which probabilities do you need in order to calculate p(getting a on 2 or fewer spins)? p(0 successes) p(1 success) p(2 successes) p(3 successes) p(4 successes) p(5 successes)

Explanation:

Step1: Define the event

The event is getting A on 2 or fewer spins out of 5 spins. This means we need to consider the cases of 0 successes (not getting A at all), 1 success (getting A once), and 2 successes (getting A twice).

Step2: Identify required probabilities

We need the probabilities of these individual cases to calculate the overall probability of the event.

Answer:

P(0 successes), P(1 success), P(2 successes)
