Answer:
2/5 or 40 percent
Step-by-step explanation:
All we need to solve this problem are the total number of boys and the total number of girls. Since we already know how many boys there are (6) , let's start by finding the girls, which is marked as b. Looking at the chart, we can tell that
8 + a = b
but we don't know what a is yet. How about we find that out first? If we look vertically, we can see that
a + 4 = 5
so
a = 1.
Now, we can find b.
b = 9
To find the probability of selecting a boy, we have to divide the number of boys by the total number of people.
boys/total = 6 / 15
Simplifying, we get the answer
2/5.
