Jamal is playing a card game with his friends. The deck has red and black cards numbered 1-12. Red cards represent negative numb

oksano4ka [1.4K]

First let us assume all black cards, the numbers that will result in 24 is:

2 * 12

3 * 8

4 * 6

Similar case with the red cards:

-2 * -12

-3 * -8

-4 * -6

Assuming the product can be negative, so we can also take the combination of two cards (1 red and 1 black):

2 * -12

3 * -8

4 * -6

-2 * 12

-3 * 8

-4 * 6

Answer:

a) P(0) = 0.6824

b) P(1) = 0.2608

c) P(2) = 0.0498

d) P(3) = 0.00635

Step-by-step explanation:

Number of units (n) in the data, n = 280

Total number of events, k = 107

The probability using Poisson probabilities is calculated using the formula;

P(x) = $\frac{e^{-\lambda}\lambda^x}{x!}$

here,

Poisson parameter, λ = $\frac{107}{280}$

Thus,

a) P(0) = $\frac{e^{-\frac{107}{280}}(\frac{107}{208})^0}{0!}$

or

P(0) = 0.6824

b) P(1) = $\frac{e^{-\frac{107}{280}}(\frac{107}{280})^1}{1!}$

or

P(1) = 0.2608

c) P(2) = $\frac{e^{-\frac{107}{280}}(\frac{107}{280})^2}{2!}$

or

P(2) = 0.0498

d) P(3) = $\frac{e^{-\frac{107}{280}}(\frac{107}{280})^3}{3!}$

or

P(3) = 0.00635
