The Department of Commerce in a state has determined that the number of small businesses that declare bankruptcy per month is approximately a Poisson distribution with a mean of 3.4. Find the probability that more than 3 bankruptcies occur next month.

0.44164

Step-by-step explanation:

Given that :

Mean (λ) = 3.4

probability that more than 3 bankruptcies occur next month

Using the poisson distribution formula :

P(x ; λ) = P[(e^-λ) * (λ^x)] ÷ x!

Probability of obtaining more than 3 bankruptcies :

To save computation time, we can use the poisson distribution calculator :

P(x >3 ; λ = 3.4)

P(x > 3) = 0.44164

P(x > 3) = 0.44164

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
