Answer 1

Answer:

Since there is only 1/5 that is the amounts of fives so it would be 1/5 divided = 0.2 times 3 = 0.6 so 0.6 is the answer

I’m really sorry if I’m wrong ...

Answer 2

A probability of 1/10 means that you expect one in ten spins to land on 2.

Performing 300 spins is the same as performing 10 spins, 30 times.

You expect to have a 2 every 10 spins, so if you repeat this process 30 times, you expect to have 2 thirty times.

In general, if you know that you have probability of success p, and you repeat the experiment n times, you expect a number of success equal to np.

In this case, p=1/10, n=300, so the expected number of successes is

$300\cdot\dfrac{1}{10}=30$
