Answer:
0.497
Step-by-step explanation:
Using the binomial probability formula :
P(x =x) = nCx * p^x * (1 - p)^(n - x)
From the question :
n = 6 ; x = 3 ; p = 0.42
P(x = 3) +... P(x = 6)
P(x = 3) = 6C3 * 0.42^3 * (1 - 0.42)^(6-3)
P(x = 3) = 20 * 0.074088 * 0.195112
P(x = 3) = 0.28910915712
Then find p(x = 4).. + p(x = 6)
Using a calculator :
P(X >= x) = 0.497
Answer:
x=6
Step-by-step explanation:
5x-4=3x+8
solve for x
2x=12
x=6
First you add up the red and black so see how many she has total.
45 + 60= 105
then if you need to find the probability of the red candies you put
45/ 105
then you can simplify it so it would be 8/21
45+60=105
45/105= 8/21
The measure of BDA is 40 degrees
Step-by-step explanation:
3 lemons = $0.99
=> 8 lemons = $0.99 * (8/3) = $2.64.
8 lemons cost $2.64.
