No - a proportional relationship would be of the form y = kx or y = k/x where k is some constant.

Nataly [62]

Answer:

a) P(Y') = 0.850

b) P(O) + P(Y) = 0.380

c) 0.001728 = 0.002 to 3 d.p

d) 0.7744 = 0.774 to 3 d.p

e) 0.120

Step-by-step explanation:

Probability of brown M&M's = P(Br) = 0.12

Probability of yellow M&M's = P(Y) = 0.15

Probability of red M&M's = P(R) = 0.12

Probability of blue M&M's = P(Bl) = 0.23

Probability of orange M&M's = P(O) = 0.23

Probability of green M&M's = P(G) = 0.15

Total probability = 1

a) The probability that a randomly selected peanut M&M is not yellow = 1 - P(Y) = 1 - 0.15 = 0.85

b) The probability that a randomly selected peanut M&M is orange or yellow = P(O) + P(Y) = 0.23 + 0.15 = 0.38

c) The probability that three randomly selected peanut M&M's are all red = P(R) × P(R) × P(R) = 0.12 × 0.12 × 0.12 = 0.001728

d) If you randomly select two peanut M&M's, compute that probability that neither of them are red

This probability = P(R') × P(R')

P(R') = 1 - P(R) = 1 - 0.12 = 0.88

P(R') × P(R') = 0.88 × 0.88 = 0.7744

e) If you randomly select two peanut M&M's, compute that probability that at least one of them is red

This probability = [P(R) × P(R')] + [P(R) + P(R)] = (0.12 × 0.88) + (0.12 × 0.12) = 0.1056 + 0.0144 = 0.120

A rectangular field has an area of 162 m2.

Fed [463]

Answer:Length: 27m

Step-by-step explanation:

the formula of area of rectangle is : width*length
so we just replace the values in the formula
162=6*Length
Length=162/6
Length=27m

Yuliya22 [10]

Answer:

1/2

Step-by-step explanation:

Simple probability is a ratio of the number of ways the thing we want to happen can to the total possible outcomes.

(For example, we flip a coin and want heads, but it can land on heads or tails. Our probability of getting heads is 1/2, one way to get heads over the 2 possible outcomes)

So for this problem, there's 20 possible things that CAN happen (3 + 7 + 10) and 10 ways we get what we want (a green marble).

Our probability of getting a green marble is $\frac{10}{20\\}$ , which simplifies to $\frac{1}{2}$
