If P(not yellow) = StartFraction 4 over 15 EndFraction, which best describes the probability of the complement of the event?

Mathematics
1 answer:
Reptile [31]3 years ago
5 0

The probability for yellow is given by 11/15.

Here, we have given that,

P(not yellow) = 4/15

Mathematically, the addition of the probability of an event and its complement adds up to be 1

The complement we have here is P(yellow)

Thus, mathematically we have;

P(not yellow) + P(yellow) = 1

<h3>What is the formula for yellow probability?</h3>

P(yellow) = 1 - P(not yellow)

From the question P(not yellow) = 4/15

Plugging this value, we have;

P(yellow) = 1 - 4/15 = 11/15

Therefore the probability for yellow is given by 11/15.

How do I do a question 5* “I, J, k, and L
7nadin3 [17]

Answer:

Step-by-step explanation:

5 (i)  243 ÷x = -81

243 ÷ -81 = x

x = -3

5 (j)  50 ÷ x = -50

    50 ÷ -50 = x

       x = -1

5(k)   -92 * x = 184

                 x = 184 ÷  -92

                 x = -2

5(l)    -800 ÷x = -20

       -800 ÷ -20 = x

       x = 40

Answer:

667 tiles

Step-by-step explanation:

To find the number of pavers, divide the total area of the patio by the area of each paver.

\text{Number of paver= $\dfrac{1800}{2.7}$}

                           = \dfrac{1800*10}{2.7*10}\\\\=\dfrac{18000}{27}\\\\= 667

valina [46]
Melissa lives 5/6 of a mile from the bus stop 5/6 of a mile is 0.83
Peter lives 2/3 of a mile from the bus stop, 2/3 of a mile is 0.66 miles
Pete does not live close to the bus stop than Melissa.
Melissa lives 0.83 - 0.66 = 0.17 miles closer to the bus stop
