Question

In a survey of 250 members of a local sports club, 150 members indicated that they plan to attend the next summer or winter olympic games, 125 members indicated that they plan to attend the next summer olympic games, and 75 indicated that they plan to attend the next winter olympic games. How many members of the club plan to attend

Answer 1

Answer:

Number of members who plan to attend both = 50

Step-by-step explanation:

n(U) = 250

n(SUW) = 150

n(S) = 125

n(W) = 75

n(SUW) = n(S) + n(W) - n(SnW)

n(SnW) = 125 + 75 - 150 = 50.
