Out of 65 players, 11 play basketball only, 11 play both basketball and cricket. The players who play cricket is twice the number of players who play basketball. By using
diagram find the number of players who play cricket only and who don't play both the game

22

Step-by-step explanation:

you see that there are 11 basketball players. So that means you need to multiply 11 and 2 which equals 22.

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
