Answer:
0.81
Step-by-step explanation:
P(success) = 0.9
P(failure) = 1 - 0.9 = 0.1
Binomial probability:
P(X=n) = nCr (0.9)^n (0.1)^r
Here, n=2 and r=0:
P(X=2) = ₂C₀ (0.9)² (0.1)⁰
P(X=2) = 0.81
Answer:
4
Step-by-step explanation:
Justin has 3 shelves and each shelf holds 5 toys.
Just has 19 toys , since each shelf can hold 5 ,
5 x 3 = 15
The three shelves will hold 15 toys.
19 - 15 = 4
4 toys will not fit into the shelves
The answer would most likely be 1 19/30
Simplify the problem down, so:
m = 12 & n = 5
<em />m = 6 & n = 2.5 <em>(divided each number by 20)
</em>
Now m is a factor of 18. Multiply each number by 3.
Answer: m = 18 & <em>n = 7.5</em>
