1 answer:

8 0

You can find the mean of negative numbers just the same as for positive numbers. It doesn't hurt for the mean to be negative.

For example, with the number -9, -5, -4, -3, -1 you can find the mean jsut as any other numbers

-9+-5+-4+-3+-1=-22

-22/5=-4.4

the mean for those set of numbers is -4.4

You are visiting a rainforest, but unfortunately,your insect repellent has run out. As a result, at each second, a mosquito land

zmey [24]

Answer:

Step-by-step explanation:

Prob at each second, a mosquito lands on your neck =0.5

Prob it bites/it lands = 0.2

Prob it does not bite/it lands = 0.8

Hence in one second prob for getting a bite = $0.5(0.2) = 0.01$

i.e. 1/100 chance of getting bitten in one second

In 100 seconds number of bites $=1$

Expected time between successive bites = 100
