Nikolai has a jar filled with 120 marbles. he has 72 red marbles, 17 blue marbles, 13 green marbles, and 18 purple marbles. what
asambeis [7]
To find the probability of both of these occurring, you will multiply the probability of choosing a blue marble by the probability of choosing a purple marble (with no replacement after the first one).

Probability of choosing a blue marble:  17/120
Probability of choosing a purple marble: 18/119

17/120 x 18/119 = 3/140

You will have a 3/140 chance of both of these occurring.

Four times the number of coins in my pocket plus five more is twenty-nine. Write an equation for the number of coins in my pocke
Lynna [10]
There are six coins already in pocket, but let’s say we don’t know it.

We would figure it out by reversing the problem. Let’s start with twenty-nine. We would subtract 5, because we are reversing. Now we have 24. Now, let’s divide by four. We would get 6.

A simpler answer would be 29 - 5 [divided by] 4 = [answer]
