Mathematics
1 answer:
skelet666 [1.2K]3 years ago
6 0

Step-by-step explanation:

just think it through. it can only be the first option. the sides 7 and 4 are together 11, and they can only meet, when putting them flat on the 11 side. but yes, if you do that, they will meet, as 11 = 11.

the result would be an extreme triangle : appearing just as one, flat line (length 11), the angles being 180°, 0° and 0°.

Suppose that P (A)=0.4 AND P (B)=0.2, If events A & B ARE Mutually EXCLUSIVE :
baherus [9]

Part (a) Finding the probability of either A or B

We are told that events A and B are mutually exclusive. This means they cannot happen at the same time. We can say P(A and B) = 0

Furthermore,

P(A or B) = P(A) + P(B) - P(A and B)

P(A or B) = 0.4 + 0.2 - 0

P(A or B) = 0.6

<h3>Answer:  0.6</h3>

=======================================================

Part (b) Finding the probability of neither A nor B

P(A or B) + P(neither A nor B) = 1

P(neither A nor B) = 1 - P(A or B)

P(neither A nor B) = 1 - 0.6

P(neither A nor B) = 0.4

The reason why this works is to imagine throwing a dart at the Venn diagram. You'll either...

  • you land in A or B (pick one but not both), OR,
  • you'll land outside both regions A and B.

One or the other must happen. Both events cannot happen simultaneously.

Answer: 615.44 cm²

Step-by-step explanation: When solving this problem the formula that you need to know is that area = π r².

The 14 cm that they are giving you is the radius of the circle, and π equals 3.14. So, in order to solve this the formula is:

Area = 3.14 x 14²

Area = 3.14 x 196

Area = 615.44 cm²
