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!

A shopkeeper bought some eggs at ¢15 each. Six of them were broken while the rest were sold at ¢20 each. If he made a profit of
zvonat [6]
In the given problem it is already stated that the cost of each eggs is 15 cent. Out the total eggs bought 6 were broken. The rest of the eggs were sold for 20 cents each and the profit made was $4.80.
Cost of the 6 broken eggs = (6 * 0.15)
                                           = 0.9 cents
Let us assume that the number of eggs bought = x
Then we can write the equation as
0.2x - (0.15x - 0.9) = 4.80
0.2x - 0.15x + 0.9 = 4.80
0.05x = 4.80 - 0.9
0.05x = 3.9
x = 3.9/0.05
   = 78
So the number of eggs bought by him is 78
