Answer:
common
Step-by-step explanation:
(u) =120
(m) =20
('s) = 50
(m n 's) =40
( m u s) = ?
we know that
(u) =(m) +('s) +(mns) + (mus)
120=20 + x +50 + x +40 +x
120 = 110 + x
x = 120 –110
x = 10 ans
Here we have selected positive numbers from 2 to 18 so there are total 17 numbers with us.
Now the prime numbers between 2 and 17 are
2, 3, 5, 7, 11, 13, 17
So there are 7 prime numbers between 2 to 18
We have to find the probability of selecting prime numbers between 2 to 18
Probability = Outcomes of interest / All possible outcomes
Probability prime = 7/17
Probability prime = 0.4117
So probability of getting prime number is 0.4117
About 38 cars. 300/8= 37.5 cars. There is no such thing as 0.5 of a car so round up to the nearest whole number.
