Question

Question 1 of 10 According to the Venn diagram below, what is P(A U B U C)?

A. 21/25

B.24/25

C.22/25

D.23/25​

Answer 1

Answer:

D. 23/25

Step-by-step explanation:

Add all the numbers inside the venn diagram for the number of outcomes

> 10+2+8+8+6+5+7 = 46

Then add all the numbers inside and outside the venn diagram for the number of possibilities

> 10+2+8+8+6+5+7+4 = 50

$p(a \: u \: b \: u \: c \: ) = \frac{total \: number \: of \: outcomes}{total \: number \: of \: possibilities}$

$p( a \: u \: b \: u \: c) = \frac{46}{50}$

$p(a \: u \: b \: u \: c \: ) = \frac{23}{25}$
