Hello!
Each time, there will be a 1/2 chance of tossing a head. Therefore, we multiply our two probabilities.
1/2(1/2)=1/4
Therefore, we have a 1/4 or 25% chance of tossing two heads in a row.
I hope this helps!
$40=T >?=m
T= $40,$80,$120,etc.
m=1,2,3,etc
P(z < 3)
From the normal distribution table,
P(z < 3) = 0.9987
the answer should be 49mm
28*7 / 4 = 49
400 times ten because when you multiply you get 40,000.
