Answer:
0.2301 = 23.01% probability that exactly 2 don't grow.
Step-by-step explanation:
For each seed planted, there are only two possible outcomes. Either it grows into a healthy plant, or it does not. The probability of a seed growing into a healthy plant is independent of any other seed, which means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which 
is the number of different combinations of x objects from a set of n elements, given by the following formula.
And p is the probability of X happening.
90% chance of growing into a healthy plant.
This means that 
12 seeds are planted
This means that 
What is the probability that exactly 2 don't grow?
So 12 - 2 = 10 grow, which is 
. Then
0.2301 = 23.01% probability that exactly 2 don't grow.
Answer:
Step-by-step explanation:
Hello there!
The first thing we want to do is find the least common denominator which would be 20
so we multiply the denominator and numerator of the fractions on the left side by 4
3x4=12
5x4=20 -12/20x
1x4=4
5x4=20 so now we would have
once again we want to isolate the variable using inverse operations
to get rid of the 4/20 we subtract each side by 4/20
now we have
now we want to get rid of the -12/20
to do so we divide each side by -12/20 (or -.6 as a decimal to make it easier)
REMEMBER flip the equality sign
we're left with
4.781, 4.782,4.783,4.784,4.785
I can't explain though:(
