Hello,
We know that the spinner has 9 numbers according to what you say.
P(spinning a 4):
1/9
P(flipping heads):
1/2
P(spinning a 7):
1/9
Also, to find the compound events of this by multiplying:
1/9×1/2×1/9=1/162. As a result, the probability of the compound event. Spinning a 4, flipping heads then spinning a 7 is 1/162. Hope it help!
