Answer:
two coins are flipped:
- if dime land heads and nickel land heads then Allan wins
- if dime land heads and nickel land tail then Beth wins
- if dime land tail and nickel land heads then Carlos wins
- if dime land tail and nickel land tail then Denesha wins
Step-by-step explanation:
The method described above is fair since the probability of each case is 0.25.
If the two coins are flipped:
- The probability dime land head is 0.5
- The probability dime land tail is 0.5
- The probability nickel land head is 0.5
- The probability nickel land tail is 0.5
Then the probability dime land heads and nickel land heads is 0.5 × 0.5 = 0.25.
The other four cases are calculated similarly and their probability is also 0.25
composite numbers less than 12={1,3,4,6,8,9,10}
The answer should be 5 or -5
70 + 130 = 200
This would be Abe’s one hour of work and the part
80 + 80 + 40 = 200
This would be Gabe’s two hours of work and the part
