For the expression to be factor-able the Discriminant , has to be greater or equal to zero
ax^2 + cx + b = 0

c^2 - 4 ab >= 0

(-3)^2 - 4 * 1 * b >= 0

9 - 4b >= 0

9 >= 4b

b <= 9/4 (2.25)

Pick any value in that range for ex:

0 , 2, -3, -6

Answer:

0.003

Step-by-step explanation:

Given: A roulette wheel consists of 38 numbers 1 to 36, 0, and double 0.

Smith bets that the outcome will be one of the numbers 1 through 12.

To find: probability that Smith will lose his first 5 bets

Solution:

Probability refers to chances of occurrence of some event.

Probability = Number of favourable outcomes/Total number of outcomes

Total number outcomes = 38

As Smith bets that the outcome will be one of the numbers 1 through 12, number of favourable outcomes is equal to 12.

So,

probability that Smith will loss his first bet = $\frac{12}{38}=\frac{6}{19}$

Therefore,

Probability that Smith will lose his first 5 bets = $(\frac{6}{19} )^5=0.003$
