The required probability is P(A and B) = 0.104
Step-by-step explanation:
Step 1 :
Given,
A , B are independent events
P(A) = 0.26
P(B) = 0.40
We need to find P(A and B)
Step 2 :
P(A and B) indicates that the event A should happen and also the event B should happen.
Since it is given that A , B are not dependent events it means that the happening of event A does not impact the happening of event B and vice versa.
Probability of 2 independent events is computed by taking the product of the 2 individual events
So here P (A and B) can be obtained as P(A) × P(B)
= 0.26 × 0.40 = 0.104
Step 3 :
Answer :
The required probability is 0.104
Answer:
He did not test it against anyone who did not drink milk before bed and he tested it on a relatively small number of people. In order to have more accurate results he should include more people in the study and should test it against the same number of people who haven't drank milk before bed. He should also take into account the amount of milk that they drank before going to bed.
There are 12 children and 15 adults at the picnic.
Add together the ratios 4 and 5 and divide the amount of people by that number (so 27 divided by 9)
You then get 3. So then multiply both sides of your ratio by 3. (4:5 ----> 12:15)
Hope this helps a little.
Answer:
Rotations are rigid transformations, which means they preserve the size, length, shape, and angle measures of the figure. However, the orientation is not preserved. Line segments connecting the center of rotation to a point on the pre-image and the corresponding point on the image have equal length. The line segments connecting corresponding vertices are not parallel.
