20 packs with only 5 chocolates
and one with 3
Answer: x = 3
Step-by-step explanation: First, isolate the x term by adding 4 to
both sides of the equation. We get 2/3x = 2.
Next, multiply both sides of the equation by the
reciprocal of 2/3 which is 3/2 to get x by itself.
So we have (3/2) 2/3x = 2 (3/2).
On the left, (3/2) 2/3 cancels and we have x.
On the right, the 2's cancel and we have 3.
So x = 3 is our answer.

Answer:
The probability that the pitcher throws exactly 8 strikes out of 15 pitches is approximately 0.199
Step-by-step explanation:
The given probability that the pitcher throws a strike, p = 0.507
The number of pitches thrown by the pitcher = 15 pitches
The probability that the pitcher does not throw a strike, q = 1 - P
∴ q = 1 - 0.507 = 0.493
By binomial theorem, we have;

When X = r = 8, and n = 15, we get;
The probability that the pitcher throws exactly 8 strikes out of 15 pitches, P(8), is given as follows
P(8) = ₁₅C₈ × 0.507⁸ × (1 - 0.507)⁽¹⁵ ⁻ ⁸⁾ = 6,435 × 0.507⁸ × 0.493⁷ ≈ 0.199
