Answer:

The events are not mutually exclusive because the P(A and B)=0.1 not 0

Step-by-step explanation:

Mutual exclusive events are those that can't happen at the same time.For example Tossing a coin, Head and Tail are mutually exclusive events because you can't get a Head and a tail at  the same time.Another example is turning left and turning right are mutually exclusive because you can't do both at the same time.

If events are mutually exclusive, they can happen at the same time.

Mathematically,the probability of mutual exclusive events follows;

P(A and B)=0 ------------The probability of A and B together equals 0

P(A or B) = P(A)+P(B)-----The probability of A or B equals the probability of A plus the probability of B.

In this question you are given;

P(A)=0.3

P(B)=0.6

P(A or B) =P(A) + P(B)= 0.3+0.6 =0.9

0.9≠0.8 thus the events are not mutually exclusive.

You pick a card at random. Without putting the first card back, you
Inga [223]

First, we need the probability of picking an odd number.

There are 5 cards in total, and 3 odd cards (3, 5, and 7).

That means that the probability that we'll draw an odd card would be \frac{3}{5}.

Then, we have 4 cards left, and 2 even cards (4 and 6), meaning that the probability that we draw an even card will be \frac{2}{4} or \frac{1}{2}.

To find the probability that these would happen in consecutive draws, we just multiply the probabilities together.

\frac{3}{5}*\frac{1}{2}=\frac{3}{10} or 0.3.

To convert this into a percentage, we multiply the decimal by 100.

0.3*100=30.

So the probability of picking an odd number and then picking an even number is 30%.

Hope this helps!

When 17 is divided by K ; where k is a positive integer less than 17 the remainder is 3 .What is the remainder when the sum of t
FinnZ [79.3K]

Answer:

The remainder is 4.

Step-by-step explanation:

Note: This question is not correctly stated. It is therefore correctly restated before answering the question as follows:

When 17 is divided by k; where k is a positive integer less than 17, the remainder is 3. What is the remainder when the sum of the possible values of k is divided by 17?

The explanation of the answer is now given as follows:

Since k < 17, it implies that the possible values of k must be from between 1 and 16 inclusive.

Between 1 and 16, only 7 or 14 will give a remainder of 3 when either of them is used to divide 17. Therefore, 7 and 14 are the possible values of k.

Therefore, we have:

Sum of the possible values of k = 7 + 14 = 21

Also, we have:

Sum of the possible values of k divided by 17 = 21 / 17 = 1 with a remainder of 4.

Therefore, the remainder is 4 when the sum of the possible values of k is divided by 17.
