Sure! Let's address each part of the question step by step.
### Part a)
How many boys can count?
To find the number of boys who can count, we look at the corresponding cell in the table. According to the table provided:
The number of boys who can count is 42.
### Part b)
What is the probability that any pupil is a boy and can count?
To determine this probability, we use the formula for probability:
[tex]\[ \text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}} \][/tex]
Here, the favorable outcome is that a pupil is a boy and can count. From the table, we know:
The number of boys who can count is [tex]\( 42 \)[/tex].
* The total number of students (possible outcomes) is [tex]\( 120 \)[/tex].
Thus, the probability is:
[tex]\[ \text{Probability} = \frac{42}{120} = 0.35 \][/tex]
So the probability that any pupil is a boy and can count is 0.35 or 35%.
