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:
Step-by-step explanation:
This is exponential growth which has the form

The answer is true (inductive reasoning is where multiple things happen at a constant rate an a conclusion is made about this)
Answer:
12
Step-by-step explanation:
Step 1:
They spilt 1/5 on the way to the lemonade stand.
180 x 1/5
= 180/5
= 36
So they spilt 36 cups of lemonade on the way to the stand.
Number of cups left = 180 - 36
= 144
Step 2:
They sold 75% of 144 cups of lemonade
75/100 x 144 (divide both 75 and 100 by 25)
= 3/4 x 144 (divide 144 by 4)
= 3 x 36
= 108
So they sold 108 cups of lemonade.
Number of cups left = 144-108
= 36
Step 3:
They spilt 1/3 of 36 cups of lemonade on the way home.
36 x 1/3
= 36/3
= 12
Therefore they brought back 12 cups of lemonade home.
The first and fourth equations justify this.
