Answer:
a. P(X=50)= 0.36
b. P(X≤75) = 0.9
c. P(X>50)= 0.48
d. P(X<100) = 0.9
Step-by-step explanation:
The given data is
x 25 50 75 100 Total
P(x) 0.16 0.36 0.38 0.10 1.00
Where X is the variable and P(X) = probabililty of that variable.
From the above
a. P(X=50)= 0.36
We add the probabilities of the variable below and equal to 75
b. P(X≤75) = 0.16+ 0.36+ 0.38= 0.9
We find the probability of the variable greater than 50 and add it.
c. P(X>50)= 0.38+0.10= 0.48
It can be calculated in two ways. One is to subtract the probability of 100 from total probability of 1. And the other is to add the probabilities of all the variables less than 100 . Both would give the same answer.
d. P(X<100)= 1- P(X=100)= 1-0.1= 0.9
Answer:
1/6
Step-by-step explanation:
A and E are vowels so you minus it by 8, which makes it 6.
SA= 2LW + 2LH + 2WH
Substituting for the values, SA = 900 cm^2
A=3 and B=1. comment if you would like me to explain how I did it.
Hey there! A dozen rolls = 12 rolls, of means multiply, we are going to multipy 3/4 by 12, make 12 a fraction, 12=12/1. Now, we can multiply 3/4 by 12/1. 3/4×12/1=36/4. Simplify 36/4 to 9. So, Raymond bought 9 rolls.
