Which event has a probability closest to 1? choosing a boy randomly in a class of 10 boys and 10 girls, drawing a heart randomly out of a pile of 4 hearts and 8 spades, correctly choosing a random number between 1 and 10, choosing a girl randomly in a class of 8 girls and 12 boys

Choosing a boy randomly in a class of 10 boys and 10 girls

Step-by-step explanation:

The probability of  choosing a boy randomly in a class of 10 boys and 10 girls is calculated as;

(number of boys)/ (total number of students in the class)

= 10/(10+10) = 10/20 = 1/2

The probability of drawing a heart randomly out of a pile of 4 hearts and 8 spades is calculated as;

4/(4+8) = 4/12 = 1/3

The probability of correctly choosing a random number between 1 and 10 is simply 1/10 since the numbers are have a uniform distribution and thus equally likely to be selected.

The probability of choosing a girl randomly in a class of 8 girls and 12 boys is calculated as;

(number of girls)/ (total number of students in the class)

= 8/20 = 2/5

Thus choosing a boy randomly in a class of 10 boys and 10 girls is the event which has a probability closest to 1.

3 is greater then both of those numbers
