A salesperson found that there was a 1% chance of a sale from her phone solicitations. Find the probability of getting 5 or more sales for 2000 telephone calls.

P(X ≥ 5) = 0.99972

Step-by-step explanation:

From the given data;

Mean

Mean

Standard deviation

4.44972

P(X ≥ 5) ; The discrete distribution by continuous  normal distribution for P(X ≥ 5) lies between 4.5 and 5.5. Hence, Normal distribution x = 4.5 since greater than or equal to is 5 relates to it.

Now;

z = −3.45

P(X > 4.5) = P(Z > -3.45)

P(X > 4.5) = 1 - P (Z < - 3.45)

From Normal  Z tables;

P(X > 4.5) = 1 - 0.00028

P(X > 4.5) = 0.99972

P(X ≥ 5) = 0.99972

the cat is blue because the probability of extension towards the prefix of the diameter of the circle could only mathematically equal to the sum of the roots of the carrots from   your garden.

step-by-step explanation:

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled
