A number is picked randomly in the range [0,7]. What is the probability that the number picked is between 3 and 5? What is the p

Answer:

(1) 0.125

(2) 0.125

Step-by-step explanation:

The total number of possible outcomes is:

N = 8

(1)

Compute the probability that the number picked is between 3 and 5 as follows:

Number of Favorable outcomes = 1

The probability is:

P (Number picked is between 3 and 5) = 1/8 = 0.125

Thus, the probability that the number picked is between 3 and 5 is 0.125.

(2)

The number usually picked appears to be in in the range [3,5], i.e. the numbers could be, {3, 4 or 5}.

Number of Favorable outcomes = n (Number < 4 and within [3, 5]) = 1

P (less than 4 ∩ within [3, 5]) = 1/8 = 0.125

Thus, the probability that the number picked is less than 4 knowing that the number usually picked appears to be in in the range [3,5] is 0.125.

Slav-nsk [51]

Answer: The dimensions of rectangle are 32 feet and 16 feet.

Step-by-step explanation:

Let the width of rectangle be 'x'.

Let the length of rectangle be '2x'.

Perimeter of fence = 96 feet

As we know the formula for "Perimeter":

$Perimeter=2(l+b)\\\\96=2(2x+x)\\\\\dfrac{96}{2}=3x\\\\48=3x\\\\x=\dfrac{48}{3}\\\\x=16\ ft$

Hence, the length of rectangle is 2x=2×16 = 32 feet and width is 16 feet.

Therefore, the dimensions of rectangle are 32 feet and 16 feet.
