============================================
Explanation:
Assuming each kick is independent of any other, this means the probability of making two field goals in a row is 0.8*0.8 = 0.64
The probability of missing any single field goal is 1-0.8 = 0.2; so the probability of missing two in a row is 0.2*0.2 = 0.04
----------------
Extra info:
Adding up those results shows that 0.64+0.04 = 0.68 is the probability of either making 2 in a row or missing 2 in a row; that leaves 1-0.68 = 0.32 to represent the probability of making exactly one field goal in either order.
Or you could note that 0.8*0.2+0.2*0.8 = 0.32
Remark
This may be a little confusing, but because they are travelling in opposite directions, the distances add when you want to get how far apart they are.
d1 + d2 = 1541
Equation
Let the time this happens = t
d1 = 323*t
d2 = 347*t
323*t + 347*t = 1541 Combine like terms on the left.
670t = 1541 Divide by 670
t = 1541/670
t = 2.3 hours pass before the distance of 1541 miles are between the two planes. You might need the answer to be 2 hours 18 minutes.
