A sample space S yields nine equally likely events, P, R, S, T, U, V , W, X, and Y.
a. Find P(T). (Round your answer to 2 decimal places.)
b. Find P(R^c). (Round your answer to 2 decimal places.)
c. Find P(P U S U U). (Do not round intermediate calculations. Round your answer to 2 decimal places.)

a. 0.11

b. 0.89

c. 0.33

Step-by-step explanation:

The sample space is an equiprobable sample space since all events have equal probabilities. Let's denote each probability by . The sum of all probabilities of the events in the sample space is 1.

a. since the events have the same probability.

b. is the probability of not occurring. Hence, it is the probability of any of the other events.

c.

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
