If A and B are independent events, P(A) = 0.25, and P(B) = 0.3, what is P(AB)?

Marrrta [24]

Answer:

$P(A) = 0.25, P(B= 0.3$

And if we want to find $P(A \cap B)$ we can use this formula from the definition of independent events :

$P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075$

And the best option would be:

$P(A \cap B) =0.075$

Step-by-step explanation:

For this case we have the following events A and B and we also have the probabilities for each one given:

$P(A) = 0.25, P(B= 0.3$

And if we want to find $P(A \cap B)$ we can use this formula from the definition of independent events :

$P(A \cap B) =P(A) *P(B) = 0.25*0.3= 0.075$

And the best option would be:

$P(A \cap B) =0.075$

cam lobes are on sale at 4 different grocery stores. which store offers the lowest unit rate for cantaloupes in dollars per poun

timofeeve [1]

Answer:

Store 2

Step-by-step explanation:

Given

1. $4.50 for 5 pounds

2. $1/5 for 1/3 pounds

3. $4.00 for 5 pounds

Required

Determine the store with the lowest unit rate

To do this, we simply divide the price by the weights in each store

For Store 1:

$Unit\ Rate = \frac{\$4.50}{5\ lb}$

$Unit\ Rate = \$0.9/lb$

For Store 2:

$Unit\ Rate = \frac{\$1/5}{1/3\ lb}$

$Unit\ Rate = \$0.6/lb$

For Store 3:

$Unit\ Rate = \frac{\$4.00}{5\ lb}$

$Unit\ Rate = \$0.8/lb$

<em>Comparing the unit rates of the three stores, we can conclude that store 2 offers the least unit rate</em>
