There are 5 consonants (B, C, D, F, G) out of a total of 8 letters on the spinner. Therefore, the probability of spinning on a consonant in one spin is 5/8.
Expected number of spins on a consonant in 160 spins:
= (5/8) x 160
= 100
Therefore, you can expect to spin on a consonant 100 times in 160 spins.
A spinner has 8 equally sized sections labeled as A, B, C, D, E, F, G, H. In 160 spins, how many times can you expect to spin on a consonant

A single coin is tossed 300 times. Heads were observed 180 times. What is the long-run relative frequency of tails?
The long-run relative frequency of an event is the ratio of the number of times the event occurs to the total number of trials in the long run.
In this case, the coin is tossed 300 times and heads were observed 180 times. Therefore, the number of times tails were observed is:
300 - 180 = 120
The long-run relative frequency of tails is:
120/300 = 0.4 or 40%
Therefore, the long-run relative frequency of tails is 40%.
In this case, the coin is tossed 300 times and heads were observed 180 times. Therefore, the number of times tails were observed is:
300 - 180 = 120
The long-run relative frequency of tails is:
120/300 = 0.4 or 40%
Therefore, the long-run relative frequency of tails is 40%.
