A candy company claims that 20% of the candies in its bags are colored green. Steve buys 30 bags of 30 candies, randomly selects

Allisa [31]

Answer:

The probability of Steve agreeing with the company’s claim is 0.50502.

Step-by-step explanation:

Let <em>X</em> denote the number of green candies.

The probability of green candies is, <em>p</em> = 0.20.

Steve buys 30 bags of 30 candies, randomly selects one candy from each, and counts the number of green candies.

So, <em>n</em> = 30 candies are randomly selected.

All the candies are independent of each other.

The random variable <em>X</em> follows a binomial distribution with parameter <em>n</em> = 30 and <em>p</em> = 0.20.

It is provided that if there are 5, 6, or 7 green candies, Steve will conclude that the company’s claim is correct.

Compute the probability of 5, 6 and 7 green candies as follows:

$P(X=5)={30\choose 5}(0.20)^{5}(1-0.20)^{30-5}=0.17228\\\\P(X=6)={30\choose 6}(0.20)^{6}(1-0.20)^{30-6}=0.17946\\\\P(X=7)={30\choose 7}(0.20)^{7}(1-0.20)^{30-7}=0.15328$

Then the probability of Steve agreeing with the company’s claim is:

P (Accepting the claim) = P (X = 5) + P (X = 6) + P (X = 7)

= 0.17228 + 0.17946 + 0.15328

= 0.50502

Thus, the probability of Steve agreeing with the company’s claim is 0.50502.

What is the solution to the expression Negative 2 minus 3 minus (negative 4)? A number line going from negative 10 to positive 1

beks73 [17]

The solution of the expression is -1 ⇒ 3rd answer

Step-by-step explanation:

Let us revise some important rules on the number line

If we add number to another number we move to right
If we subtract a number from another number we move to left

∵ The expression is negative 2 minus 3 minus (negative 4)

∵ negative 2 = (-2)

∵ minus means (-)

(-2) minus 3 means move 3 units from (-2) to left, so you will pass -3, -4, and stop at -5

∴ (-2) - 3 = -5

∵ minus (negative 4) = - (-4)

- Remember (-)(-) = (+)

∴ minus (negative 4) = + 4

That means move 4 units to the right from -5, then you will pass -4, -3, -2, and stop at -1

∴ -5 + 4 = -1

∴ The expression (-2) - 3 - (-4) = -1

The solution of the expression is -1
