Answer:
0.234
Step-by-step explanation:
Given that:
Proportion, (p) ; Islanders beat rangers = 5/6 = 0.8333
Probability that islander win exactly 5 out of 7 games
1 - p = 0.1667
Usingbthe binomial distribution formula :
P(x =x) = nCx * p^n * (1 - p)^(n - r)
P(x = 5) = 7C5 * 0.833^5 * 0.1667^2
P(x = 5) = 21 * 0.833^5 * 0.1667^2
P(x = 5) = 0.23405369484362783281917
P(x = 5) = 0.234
Answer:
a = -3 and b=5
Step-by-step explanation:
Given that 10 can be written as 2*5 or √2*√2*5, and √18 can be written as √(2*9) or √2*√9 or 3√2, you can write the fraction as:
So getting rid of the √2 factor, you get 5√2 - 3, so a=-3 and b=5
Let's expand the products they are all in the form
For the first one we have a=x and b=2i:
For the second one we have a=x-2 and b=2i:
For the third one we have a=x+1 and b=i:
