Answer:
Explained below.
Step-by-step explanation:
A compound event is an event in which has possible outcomes more than one.
To determine the probability of compound events on has to compute the sum of the probabilities of all the individual events and, if required, remove any coinciding probabilities.
Examples of compound events are:
- The events of roll a five using a 6-sided die
.
The number of favorable outcome is rolling a 5, is 1.
The total number of outcomes of rolling a die is 6.
Then the probability of rolling a 5 is 1/6.
- The events of pulling a heart out of a standard deck of cards
The number of favorable outcome of pulling a heart is 13.
The total number of outcomes is 52.
The probability of pulling a heart from a standard deck is 13/52 or 1/4.
Thus, the procedure is to compute the sum of the probabilities of all the individual events and, if required, remove any coinciding probabilities.
Answer:
She used 6.825 pints of withe paint to paint her bedroom walls
Step-by-step explanation:
We know Cathy used 9.1 pints of paint and 1/4 is blue.
first we have to calculate the white paint, we are going to calculate it by subtracting 1/4 of the total paint
1 - 1/4 = 4/4 - 1/4 = 3/4
Now that we know that 3/4 of the total paint is white, we have to multiply it by the amount of paint so we get how many pints of paint are white
3/4 * 9.1 = 6.825
She used 6.825 pints of withe paint to paint her bedroom walls

The probability of drawing two blue marbles if the first marble is not replaced is 1/5
<h3>How to determine the probabilities?</h3>
<u>The probability of tossing a head and drawing a red marble</u>
The given parameters are:
White = 1
Blue =3
Red = 2
Total = 6
The probability of a head is
P(Head)= 1/2
The probability of drawing a red marble is
P(Red)= 2/6 = 1/3
The required probability is
P = P(Head) * P(Red)
This gives
P = 1/2 * 1/3
P =1/6
<u>The probability of drawing two blue marbles if the first marble is not replaced.</u>
Here, we have:
P(B1) = 3/6 = 1/2
P(B2) = 2/5
The required probability is
P = P(B1) * P(B2)
This gives
P = 1/2 * 2/5
P =1/5
Hence, the probability of drawing two blue marbles if the first marble is not replaced is 1/5
