Answer:
The probability of spinning an even number and flipping heads is 1/4
Step-by-step explanation:
You spin the spinner and flip a coin.
A spinner that has 1 of each number, 1-6
Total events =12
(1,H),(2,H),(3,H),(4,H),(5,H),(6,H)
(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)
We are supposed to find probability of spinning an even number and flipping heads
Favorable events : (2,H),(4,H)(6,H) = 3
Total events = 12
The probability of spinning an even number and flipping heads =
Hence The probability of spinning an even number and flipping heads is 1/4
It is
The equation for area of a trapezoid is
Substituting our values in
We can then simplify the expression
