The probability that the sum of Michelle's rolls is 4 is 0.083
∴ P(A)=0.083
Step-by-step explanation:
Given that Michelle is rolling two six-sided dice, numbered one through six.
To find the probability that the sum of her rolls is 4:
∴ n(s)=36
Let P(A) be the probability that the sum of her rolls is 4
Then the possible rolls with sums of 4 can be written as
n(A)=3
The probability that the sum of her rolls is 4 is given by
=0.083
∴ P(A)=0.083
∴ the probability that the sum of Michelle's rolls is 4 is 0.083

Answer: 3/5
Step-by-step explanation:
Fist find out how many whites are there and divide it by the total to find the probability.
9/15 simplify it to 3/5
-6 + 7 = 1 and -6*7 = -42
So f(x) = (x + 7)(x - 6)
Answer:
B
Step-by-step explanation:
first make each equation 'y='.
then if you times each x value by each other it has to equal '-1'.
so for B, itll be y=1/3x-11/3 and y=-3x+23.
1/3 x -3 = -1
It will take 30 more minutes to fill up the pool completely.
2/3 of the pool has been filled in 1 hour. This equates to 60 minutes. This means that in 30 minutes, 1/3 of the pool has been filled. Another 30 minutes and 2/3 of the pool has been filled.
Finally, another 30 minutes will mean that the whole pool is filled.
