Answer:
The probability that a corn crop has either an ear worm infestation, a corn borer infestation
P(EUB) = 0.27
Step-by-step explanation:
<u>Explanation</u>:-
<u>Addition theorem on probability</u>:-
If S is a sample space, and E , F are any events in S then
P(EUF) = P(E) +P(F) -P(E n F)
Let 'E' be the event that a corn crop has an infestation of ear worms
let 'B' be the event that a corn crop has an infestation of corn bores
P(EUB) = P(E) +P(B) -P(E n B)
given P(E) = 0.24 and P(B) = 0.16 and P(E n B) =0.13
P(EUB) = P(E) +P(B) -P(E n B)
P(EUB) = 0.24 + 0.16 - 0.13
= 0.27
The probability that a corn crop has either an ear worm infestation, a corn borer infestation
P(EUB)=0.27
It’s 3!! I checked on a calculator :)
Answer: 27
Step-by-step explanation:
The perimeter is the lengths of all sides of the figure added together. Since all sides are equal in this triangle, we know all sides have a length of 9. We know this because all sides have 2 little lines on them, symbolizing that they are equal.
P=9+9+9=27

Answer:
-2.5
Step-by-step explanation:
Here in this question, we are interested in calculating the z-score for a student that had a particular mark at the test
To calculate the z-score, we need to use a mathematical formula
Mathematically;
z-score = (x - mean)/SD
From the question;
x = 76
mean = 86
standard deviation SD = 4
Plugging these values in the equation, we have;
z-score = (76-86)/4 = -10/4 = -2.5
