Answer:
Rachel drove on Saturday = 503 miles
Rachel drove on Sunday = 438 miles
Step-by-step explanation:
As given , Rachel drove 65 miles less on Sunday than she did on Saturday.
Let us suppose
Rachel drove on Saturday = x
Rachel drove on Sunday = y
then, we get
y = x - 65
Also given, If twice the miles was driven on Sunday is 373 more than the number of miles driven on Saturday
then , we get
2y = 373 + x
⇒2(x - 65) = 373 + x
⇒2x - 130 = 373 + x
⇒2x - x = 373 + 130
⇒x = 503
∴ we get
Rachel drove on Saturday = x = 503
Rachel drove on Sunday = y = x - 65 = 503 - 65 = 438
Answer: a. 0.1252
b. 0.04736
Step-by-step explanation:
Let X denotes a the number of soldiers killed by horse kicks in a year such that it has a Poisson distribution with mean .
Poisson distribution formula:
a.
Hence, the probability of more than 1 death in a corps in a year= 0.1252
b. For five years, Mean =
Hence, the probability of no deaths in a corps over five years = 0.04736
