P(H,H,H)=P(H,T,H)
This is classical probability, so the probability of an event is the number of "favorable" events over total events.
The total number of events, by the counting principle, is 2^3=8.
The total number of events remains the same for P(H,H,H) and P(H,T,H), as you're still flipping 3 coins with two sides.
For P(H,H,H) the favorable event is (H,H,H) so 1, for P(H,T,H) the favorable event is (H,T,H) also one.
Conclusion:
P(H,H,H)=P(H,T,H)=1/8

Answer:
x = -1
Step-by-step explanation:
Distribute by multiplying -5x by 2 and 4 by 2, leaving you with -10x+8+4-5=-3, then solve leaving you with x = -1.
Adam pays for 2/5 of the meal so his father pays for 3/5
3/5 = 52.50
1/5 = 52.50 / 3 = 17.50
so cost of the meal = 5 * 17.50 = $87.50
