The number of typing errors on a page follows a Poisson distribution with a mean of 6.3. Find the probability of having exactly six (6) errors on a page.

0.1595

Step-by-step explanation:

Poisson Distribution Formula

Here,

x= 6

Hence, the probability of having exactly six (6) errors on a page = 0.1595

y < -3

step-by-step explanation:

-3y - 2 > 7

-3y -2 + 2 > 7+2

-3y > 9

-3y/-3 < 9/-3   (change the inequality sign when multiplying or dividing by a negative number)

y < -3
