Among a group of 60 engineering students, 24 take math and 29 take physics. Also 10 take both physics and statistics, 13 take bo

ivolga24 [154]

Answer:

a) 26

b) 0.3076

Step-by-step explanation:

We are given the following in the question:

M: Math

P: Physics

S: Statistic

n(Math) = 24

n(Physics) = 29

$n(P\cap S) = 10$

$n(M\cap P) = 13$

$n(M\cap S) = 11$

$n(M\cap P\cap S) = 8$

$n(M'\cap P'\cap S') = 7$

a) Number of students who take statistics

Formula:

$n(P\cup M\cup S)=\\n(P)+n(M)+n(S)-n(P\cap M)-n(P\cap S)-n(M\cap S)+n(P\cap M\cap S)$

Putting the values, we get,

$n(P\cup M\cup S) = n - n(P'\cap M'\cap S') = 60-7 = 53$

$53 = 24 + 29 + n(S) -10-13-11+8\\n(S) = 53-24-29+10+13+11-8\\n(S) = 26$

Thus, 26 students took statistic.

b) probability that a student selected at random takes all three, given he takes statistics

$p(\text{All three subject}|\text{Statistic})\\\\=\displaystyle\frac{n(P\cap M\cap S)\cap n(S)}{n(S)}\\\\= \frac{8}{26} = 0.3076$
