8+0.75x=25
0.75x=25(-8)
0.75x=17
17/0.75= 22.666
He can ride a total of 22 rides
Answer: The probability that the sum is less 7 or less is 20/51.
First, we start by selecting an ace because the question says one card is an ace. Therefore, our final probability is out of 51.
Our goal is to have 7 or less. That means we can draw a 2, 3, 4, 5, or 6. Since, there are 4 of each type, we have 4 x 5 = 20 different possibilities.
Answer:
5
Step-by-step explanation:
7*4= 28
5+2=7
7*4=28
28=28
From the Pascal's triangle, take the correct level. Use it to write the binomial expansion. Or use nCr.
(x+y)^n
Remember that the powers of x start at n, and that the sum of the x and y powers is always n.
