Answer:
D
Step-by-step explanation:
Probability that the die will show an even number
in one rolling is 3/6=0,5 = p
We have formula for repeating rolling
n!/(r!(n-r)!) p^r (1-p)^(n-r)
n = how many times we repeat rolling = 6
r = how many times we want something to happen
(show an even number exactly two times) = 2
15 *(0,5)^2 *(0,5)^4 = 0,234375
12a
math: 68/85 * 100 = 80%
science: 70*0.9 = 63 number correct
b. Science
c.48
Answer:
6/5
Step-by-step explanation:
rise/run
I hope this is right! :D
First you need to find a common denominator. 11/15 = 22/30
3/10= 9/30
9/30+22/30= 1 1/30
Hope this helps!
