Either heads or tails so there is a 50/50 chance of both
Average is the total of x divide by number of x.
Here, we have,
x = 55, 64, 60, 61
number of x = 4
Total of x = 55 + 64 + 60 + 61 = 240
So, the average is,
240 / 4 = 60
Total number of lollipops = 35
P(selects a grape ) = 10/35
P( then selects an apple) = 18/34
Required probability = 10/35 * 18/34 = 18/119 = 15.1% answer
