+168 Some of the children at the nursery arrive by car.
40% of the children are boys
70% of the boys arrive by car
60% of the girls arrive by car
What is the probability that a child chosen at random from the nursery will arrive by car
Let us see if I can figure this one out!
Will assume that there are 100 kids.
100 x 40% =40 of them are boys
40 x 70% = 28 boys arrive by car.
100 - 40 = 60 - Number of girls in Nursery.
60 x 60% = 36 of them arrive by car.
28 boys + 36 girls = 64 - kids that arrive by car.
64 / 100 = 64% - probability of a randomly picked kid that he/she arrived by car.
