Agiven binomial experiment has n=100 trials and p=1/3. is it more likely to get x=20 successes or x=45 successes. why?

The P(x=45) is more that the P(x=20). Therefore x=45 successes is more likely to get.

Step-by-step explanation:

Given information: n=100 and p=1/3.

According to the binomial distribution, the probability of getting r success in n trials is

where, n is total trials, p is probability of success and q is probability of failure.

Total trials, n = 100

Probability of success, p =

Probability of failure, q =

The probability of 20 successes is

The probability of 45 successes is

The P(x=45) is more that the P(x=20). Therefore x=45 successes is more likely to get.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
