Answer: 0.49
Step-by-step explanation:
The mean= E[x]=1/l= 7.5 min
l=1/7.5 =10/75=2/15
The exponential distribution's probability density function is looking like that:
F(x)= l*e^(-l*x) = 2/15*e^(-2*x/15)
P(0<x<5)= e^(-0*2/15)- e^(-5*2/15)=1- e^(-2/3)= approx 0.49
There’s not graph so if you could provide a graph
Answer:
part a
The probability of getting a 2 is 1/6 and the probability of getting a head is 1/2. The probability of getting both is thus 1/6 x 1/2= 1/12
part b
The probability of getting an even number is 3/6 = 1/2. The probability of getting a tail is 1/2. The probability of getting both is thus 1/2 x 1/2= 1/4.
