Question

The table gives the information of indoor sports selected by girls and boys of grade 7.
Chess is to be selected by the girls.

• A. unlikely
• B. certainly
• C. likely

Answer 1

The correct option is A unlikely

An event is likely to happen when the probability of occurence of that event is more than 0.5.

$\text{P(Event)}=\frac{\text{Number of times the event occurs}}{\text{Total number of trials}}$

Total number of students = 73.

Boys and chess:

$\text{P(Boys, Chess)}=\frac{39}{73}=0.53$

0.53 implies, it is likely to happen that boys are like to select chess as their indoor game.

Girls and chess:

$\text{P(Girls, Chess)}=\frac{13}{73}=0.18$

0.18 implies, it is unlikely to happen that girls are unlikely to select chess as their indoor game.
