Kevin is 3 years older than Daniel. Two years ago, Kevin was 4 times as old as
Korvikt [17]

Answer:

k - 2 = 4d - 8

d + 1 = 4d - 8

Step-by-step explanation:

Daniel's age = d

Kevin's age = k

Given that, k = d + 3 -------------- (1)

Two years ago, the age of Daniel = d - 2

Two years ago, the age of Kevin = k - 2

Since,  two years ago, Kevin was 4 times as old as

Daniel, k - 2 = 4(d - 2)

Opening the bracket,

k - 2 = 4d - 8

Since the value of k is d + 3 (see (1))

d + 3 - 2 = 4d - 8

d + 1 = 4d - 8

(I am just giving the answer cause I LOVE Linear Equation )

1 + 8 = 4d - d

9 = 3d

9/3 = d

3 = d

Therefore, Daniel's present age is 3 and Kevin's present age = 6

Hope You understood

Thank You

An urn contains 13 red marbles and 11 blue marbles. 12 marbles are chosen at random. What is the probability that 7 red marbles
algol13

The probability of selecting or choosing seven marbles is 0.29.

Let E be the event of choosing seven red marbles.

According to the given.

Total number of balls in an urn = 13 + 11 = 24

Total number of red marbles = 13

Total number of blue marbles = 12

Now, the total number of ways of selecting 12 marbles from 24 = ^{24} C_{12}

And the number of ways of selecting 7 red marbles = ^{13} C_{7} \times ^{11} C_{5}

As, we know that, the probability of any event can be calculated as by taking the ratio of favroble outcomes to the total number of outcomes.

Therefore, the probability of selecting or choosing seven marbles is given by

P(E) = \frac{^{13}C_{7}\times\ ^{11} C_{5}   }{^{24} C_{12} }

⇒ P(E) = \frac{\frac{13!\times11!}{7!\times6!\times 5!\times6! } }{\frac{24!}{12!12!} }

⇒ P(E) =  792792/2704156

⇒P(E) = 0.29

Hence, the probability of selecting or choosing seven marbles is 0.29.
