Answer: 0.76

Step-by-step explanation:

Given : Number of sections ( yellow, brown, red and orange) = 4

The spinner is spun 50 times and lands on brown 12 times, then the number of times spinner does not land on brown = 50-12=38

Then, the experimental probability that the spinner does not land on brown :_

\dfrac{\text{Spinner does not land on brown}}{\text{Total spins}}\\\\=\dfrac{38}{50}=0.76

Hence, the experimental probability that the spinner does not land on brown = 0.76

A homeowner finds that there is a 0.15 probability that a flashlight does not work when turned on. If she has three flashlights,
prohojiy [21]

Answer:

A) 0.386

B).0.325

Step-by-step explanation:

probability p will not work = 0.15

Q probability w5ill work = 0.85

Number of flashlight = 3

Probabilty of at least one=

1- probability of none

But probability of none= 3C0(p)^0(q)^3

= 1*(0.15)^0(0.85)^3

= 1*1*(0.614)

= 0.614

Probability of at least one=1-0.614

= 0.386

Probability of two flashlight work

= 3C1(0.15)^1(0.85)^2

= 3*(0.15)*(0.7225)

= 0.325
