Answer:
0.07
Step-by-step explanation:
According to the Question,
Let C denote the event that a student takes calculus & S denote the event that a student is on scholarship.
- Given, The probability that a student takes calculus or is on scholarship is 0.85 [P(C ∪ S)=0.85] . The probability that a student is on scholarship is 0.61 [P(S)=0.61] . and the probability that a student is taking calculus is 0.31 [P(C)=0.31] .
We have,
⇒P(C ∪ S)=0.85 , P(C)=0.31 , P(S)=0.61
We Know, P(C∩S) = P(C) + P(S) − P(C∪S)
Then, Put the Above Values in the Equation, we get
So, P(C∩S) = 0.31 + 0.61 - 0.85 ⇒ 0.07
- Thus, The probability that the student is taking calculus and is on scholarship is 0.07
