Answer:
.43
Step-by-step explanation:
if you multiply something by 1/2, the product is half of that something.
if you multiply b by 1/x, the product is one x of b.
if you multiply anything by 1/4, the product is one quarter of anything.
Probability of 1st number being even : 3/7
probability of 2nd number being even : 2/6
probability of 3rd number being even : 1/5
probability of all 3 numbers being even : 3/7 * 2/6 * 1/5 = 6/210 = 1/35
As 300 tickets are sold , the probability of being a winner is = 
The prize value is $64 or 
= 0.213
The cost of ticket you paid = $4
Hence, the expected value of one ticket = 0.213-4 = -3.787 or rounding off we get -3.79
The area would be 128ft^2 because 2^4 is 2x2x2x2 and 2^3 is 2x2x2 and if you multiply them you get 128ft6=^2
