Question

The probability distribution histogram shows the weight distribution of the pumpkins in a competition at a state fair.

What is P(70≤X<110) ?

Answer 1

`\mathbb P(70\le X<110)=\mathbb P(70\le X<80)+\mathbb P(80\le X<90)+\mathbb P(90\le X<100)+\mathbb P(100\le X<110)`

`=0.10+0.15+0.15+0.25`

`=0.65`
