8.75 * 20 = 175

8 * 20 = 160

175 - 160 = 15

He'd make $15 more working at the amusement park.

Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.

3280 * 2 = 6560 (is what she makes per month)

6560/4 (because 4 weeks in a month) = 1640

OR (An alternative method.)

3280/2 = 1640

She'll be paid $1640 per week.

105,000/12 (12 months in 1 year) = 8750 (He makes this per month)

8750 * 2 = 17500

He makes 17500 semi monthly

8750 /4 = 2187.5

2187.5 * 2 (because bi-weekly) = 4375

He makes 4375 bi-weekly

8750/4 = 2187.5

He makes 2187.5 every week

Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.

Assume that X is a binomial random variable with n = 27 and p = 0.90. Calculate the following probabilities. (Do not round inter

Yuki888 [10]

Answer:

a) $P(X=26) = 27C26 (0.9)^{26} (1-0.9)^{27-26}= 0.1744$

b) $P(X=25) = 27C25 (0.9)^{25} (1-0.9)^{27-25}= 0.2520$

c) $P(X=25) = 27C25 (0.9)^{25} (1-0.9)^{27-25}= 0.2520$

$P(X=26) = 27C26 (0.9)^{26} (1-0.9)^{27-26}= 0.1744$

$P(X=27) = 27C27 (0.9)^{27} (1-0.9)^{27-27}= 0.0582$

And addind the values we got:

$P(X\geq 25)= P(X=25)+P(X=26)+P(X=27)=0.2520+0.1744+0.0582=0.4846$

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".

Solution to the problem

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=27, p=0.9)$
