60 * 100 / 65 = 92.31
100% - 92.31% = 7.69%
Answer: Decrease 7.69%
The probability you will roll a sum of 9 is 1/4.
<h3>What is the probability?</h3>
Probability determines the chances that an event would happen. The probability the event occurs is one and the probability that the event does not occur is 0. The more likely the event is to happen, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
The probability you will roll a sum of 9 = total times a sum of 9 is derived / total sample spaces
- total times a sum of 9 is derived = (3 + 6) , (6 + 3) , (4 + 5) , (5 + 4)
- Total sample spaces = 36
The probability you will roll a sum of 9 = 4/36 = 1/9

The total cost of rice and beans bought by Gabriel is 6b + 4r.
The simplified expression of the final cost is 4b + 3r.
<h3>What is simplification?</h3>
Simplification can be defined as a process of replacing a mathematical expression by the cancellation of common factors, regrouping of terms in the same variable to get the more simple form of the given expression.
Given that
6b + 4r represents the total cost of the rice and beans Gabriel bought.
He returns 2 bags of beans and 1 bag of rice.
This can be written as,

Then, the total number of bags of rice and beans is given as,

When we simplify the above equation, we get,

Hence we can conclude that the expression for rice and beans after the return is (4b+3r).

The answer should be 70 baskets
70% is 7/10
10 x 10 = 100 baskets, so
7 x 10 = 70 expected baskets
