Given the selection of yellow marbles = 41 times.
The selection of white marble = 24 times.
Total number of selections made = 65
Now calculate the probability that the next selection will be the yellow marble. Therefore, the probability of getting yellow marble can be determined by dividing the yellow selection by total number of selections.
For this case we have the following equation:
From here, we must clear the value of y.
For this, we follow the following steps:
1) Distributive property:
2) Variable terms on one side of the equation and constant terms on the other side of the equation:
3) Algebraically add the constant terms:
4) Pass the number 20 to divide:
Answer:
The value of y is given by:
