Answer:

0.912

Step-by-step explanation:

<em>The complete question is attached.</em>

"OR" in probability means "ADDITION". So we find the individual probabilities and "ADD" them.

P(Plan A) would be the total people for plan A (add up column of Plan A) divided by total number of people [add up all the numbers].

Looking at the table, we have:

P (Plan A) = 38/68

Now,

P(40-49 Group) can be found by adding up the row of 40-49 age group and dividing by the total. So, we have:

P(40 - 49 Group) = 24/68

Now, adding up both:

38/68 + 24/68 = 62/68 = 0.912

When will n(A∩B)=0? Explain and give an example.

andrew11 [14]

Answer:

Two sets are called disjoint if they have no elements in common. For example:

The sets S = { 2, 4, 6, 8 } and T = { 1, 3, 5, 7 } are disjoint.

Another way to define disjoint sets is to say that their intersection is the empty set,

Two sets A and B are disjoint if A ∩ B = 0.

In the example above,

S ∩ T = ∅ because no number lies in both sets.

Masteriza [31]

Answer:

Should be 5 in.

Step-by-step explanation:

C=2*Pi*R

31.4=2*3.14*R

substitute 5 for radius= 2*5=10

A weed called the raindrop vine is known for growing at a very fast rate.

Vinvika [58]

First, we need to convert 0.75 feet to inches.

0.75 feet = 9 inches

Now, we need to divide 9 by how many hours are in a day, which is 24.

9/24 = 0.375

The raindrop vine can grow up to 0.375 inches per hour.
