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
