Brian spins a fair spinner numbered 1 - 5 and flips a fair coin.

Greeley [361]

Answer: 0.1

Step-by-step explanation:

If we spin a fair spinner numbered 1 - 5 and flips a fair coin.

Then, the possible outcomes will be :-

$(1,T),(2,T), (3,T), (4,T), (5,T)\\\\(1,H),(2,H), (3,H), (4,H), (5,H)$

i.e. total 10 possible outcomes.

The favorable outcomes = a 2 and a head i.e. only 1 .

Now, the probability of obtaining a 2 and a head will be :_

$\dfrac{\text{Number of favorable outcome}}{\text{Total outcomes}}\\\\=\dfrac{1}{10}=0.1$

Hence, the probability of obtaining a 2 and a head = 0.1

Hello can you please help me posted picture of question

The area of the spinning board is divided into 10 equal sections.

Probability in this case will be = Area of favorable outcome/Total Area

Let the total area be A.
Area of each section will be A/10

So probability of landing on 3 will be = (A/10) / A = 1/10

So the correct answer will be option C
