Agroup of freshmen at a local university consider joining the equestrian team. thirty‑five percent of students choose western riding, 45% choose dressage, and 50% choose jumping. twenty percent choose both dressage and jumping, while 10% choose western and dressage. no one chooses western and jumping. there are no horses suitable for two styles, and each student is assigned to one horse.
a - what is the probability that a student chooses dressage or jumping? a) 0.95b) 0.9c) 0.23d) 0.75
b - what is the probability that a student chooses neither dressage nor western riding? a) 0.05b) 0.2c) 0.5d) 0.3

a) Option D) 0.75

b) Option D) 0.3

Step-by-step explanation:

We are given the following in the question:

Percentage of students who choose Western riding = 35%

Percentage of students who choose dressage= 45%

Percentage of students who choose jumping = 50%

Percentage of students who choose both dressage and jumping = 20%

Percentage of students who choose Western and dressage = 10%

Percentage of students who choose Western and jumping = 0%

Thus, we can say

Formula:

a) P(student chooses dressage or jumping)

b) P(student chooses neither dressage nor Western riding)

the answer is 28
