a spinner with 10 equally sized slices has four yellow slices, three red slices, and three blue slices. Martina spun the dial 500 times and got the following results. (refer to pic)answer the following. Round your answers to the nearest thousand.a) from Martinas results, compute the experimental probability of landing on red.b) assuming that the spinner is fair, compute the theoretical probability of landing on red.c) assuming that the spinner is fair, choose the statement below that is true. 1. the larger the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability. 2. the smaller the number spins, the greater the likelihood that the experimental probability will be close to the theoretical probability. 3. the experimental probability will never be close to the theoretical probability, no matter the number of spins.

A Spinner With 10 Equally Sized Slices Has Four Yellow Slices Three Red Slices And Three Blue Slices Martina Spun The Dial 500 Times And Got The Following Resul class=

Sagot :

Given the experimental results of spinning the spinner:

Yellow: 212

Red: 144

Blue: 144

The sum of times = 500

a) from Martina's results, compute the experimental probability of landing on red.

So, the answer will be probability = 144/500 = 0.288

b) assuming that the spinner is fair, compute the theoretical probability of landing on red.

As shown: the spinner has 10 equally sized slices.

The number of red slices = 3

So, the probability of red = 3/10 = 0.3

c) assuming that the spinner is fair, choose the statement below that is true.

The true statement will be:

1. the larger the number of spins, the greater the likelihood that the experimental probability will be close to the theoretical probability.
