Answer: Our required probability would be
Step-by-step explanation:
Since we have given that
Let A be the event that Kirk has the ace of spades.
Let B be the event that everyone has an ace.
So, P(A) =
P(B) =
And P(A∩B) =
So, P(Kirk has the ace of spades | each of them gets an ace)
Hence, our required probability would be

Answer:
7 is the value of x.
Step-by-step explanation:
Now we have to,
find the required value of x.
→ -18x - 19 = -145
→ -18x = -145 + 19
→ -18x = -126
→ x = -126/-18
→ [ x = 7 ]
Hence, the value of x is 7.
Answer:
200
Step-by-step explanation:
Given that :
16% of coins are quarters from 1990
Number of quarters from 1990 = 32
Since 16% = 32 quarters
The number of the total coins can be obtained thus :
Let the total number of coins = x
16% = 32
100% = x
Cross multiply :
0.16x = 32 * 1
0.16x = 32
x = 32 / 0.16
x = 200
Hence, total number of coins in the collection = 200
