Total number of outcomes of 7 from 10 = 10*9*8 / 3*2*1 = 120
probability of each outcoe is 0.85^7* (0.15)^(3) = 0.0010819
Required probability = 120 * 0.0010819 = 0.1298
Answer:
ps and qr is parellel so the 70°and x is co interior angles.
so, our equation will be look like .
70°+x=180°
x=180°-70°
x=110°
Answer:
DEF or EAD or DEA
Step-by-step explanation:
this is because you can mix up the letters and it still be a different combination with the same answer.
its like multiplication 1 times 1 times 2 equals two whether the questions is asked 1 times 2 times 1 or 2 times 1 times one
hope this helps!
The probability that he will pull out a nickel, then a quarter, then a nickel is 
<u>Explanation:</u>
Given:
Number of dimes = 3
Number of Quarters = 2
Number of pennies = 2
Number of Nickles = 5
Total coins = 3 + 2 + 2 + 5
= 12
Probability that Armando will pull out Nickel first =
After taking out Nickel, the total number of coins in the pocket will be 11
So,
Probability that he will pull a quarter = 
Total coins remaining = 11 - 1 = 10
Total Nickel remaining = 5 - 1 = 4
Probability that he will take our Nickel = 
Total probability = 
= 
Answer:

Step-by-step explanation:
The sample space for the experiment is:

- Number of elements in S, n(S)=12
Given an event E such that:

- Number of elements in E, n(E)=8
The outcomes in the complement of E are the outcomes in S that are not in E.

- Number of elements in the complement of E,

Therefore:
