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.
