Suppose that Ayumi rolls a pair of fair six-sided dice. Let A be the event that the first die lands on 2 and B be the event that

Tanya [424]

Answer:

$\frac{1}{6} ,\frac{1}{6} ,\frac{1}{36}\,,\,independent$

Step-by-step explanation:

Given: Let A be the event that the first die lands on 2 and B be the event that the second die lands on 2.

To find:

P(A), the probability that the first die lands on 2

P(B), the probability that the second die lands on 2

P(A and B): the probability that the first die lands on 2 and the second die lands on 2

Solution:

Probability refers to chances of occurrence of some event.

Probability = number of favourable outcomes/total number of outcomes

Sample space = $\left \{ 1,2,3,4,5,6 \right \}$

Total number of outcomes = 6

For P(A):

Number of favourable outcomes = 1

So,

$P(A)=\frac{1}{6}$

For P(B):

Number of favourable outcomes = 1

So,

$P(B)=\frac{1}{6}$

P(A and B) = $P(A)P(B)=\left ( \frac{1}{6} \right )\left ( \frac{1}{6} \right )=\frac{1}{36}$

Yes, A and B are independent events as happening of each of the event does not depend on the other.

Give an example of a decreasing logarithmic function that has a positive y-intercept.

Anvisha [2.4K]

Answer: f(x) = -ln(x + 1) + 3

Step-by-step explanation:

We want it to be decreasing, then we can write it, for a start, as:

f(x) = -ln(x)

Ok, now we want it to have a positive y intercept, then we can add a real number inside the logarithm, and other outside: such that f(0) = positive number.

f(x) = -ln(x + 1) + 3

Now, when x = 0 we have:

f(0) = -ln(1) + 3 = 0 + 3 = 3

Then we have a decreasing logarithmic function, with an y-intercept larger than zero.
