This is the concept of probability and statistics, we are required to calculate the following probabilities, but first we need to know that:
The probability of an arrow pointing on either A,B or C after spinning is:
P(x)=1/3
The probability of an arrow pointing on either 1,2,3,4 after spinning is:
P(y)=1/4
thus solving the question we get:
14]
P(D and 2)=P(B)*P(2)=1/3*1/4=1/12
15]
P(A and Odd #)
P(A)=1/3
P(Odd #)=2/4=1/2
thus;
P(A and Odd #)=1/3*1/2=1/6
16]
P(C and a # less than 4)
P(C)=1/3
P(# less than 4)=3/4
thus:
P(C and a # less than 4)=1/3*3/4=1/4
