Based on the venn diagram of siblings, the probability of being an only child or having only sisters is d. 0.50.
<h3>What is probability of being an only child or having a sister?</h3>
The probability of being an only child or having a sister can be found as:
= (Number of those only sister + Number of only children) / Total number of people in poll
Solving gives:
= (8 + 7) / (8 + 10 + 5 + 7)
= 15 / 30
= 0.50
In conclusion, the probability of having a brother and sister is 0.50.

Answer:
shaded/square = (50π cm²)/(400 cm²) = π/8
Step-by-step explanation:
The quarter circle has area ...
A = (1/4)(πr²) = π/4(20 cm)² = 100π cm²
The half-circle has area ...
A = (1/2)(πr²) = π/2(10 cm)² = 50π cm²
Then the area of the shaded portion is ...
shaded = 100π cm² -50π cm² = 50π cm²
__
The area of the square is ...
A = s² = (20 cm)² = 400 cm²
Then the ratio of interest is ...
shaded/square = (50π cm²)/(400 cm²) = π/8
