if a spinner has 5 colors pink,red,orange,blue,green What is the probability of landing on the pink sector? If we take 20 spins, how many times should it land on pink? (theoretical probability)
The probability of landing on the pink sector is 1/5, since there are 5 possible outcomes and only 1 of them is pink.
In 20 spins, it is expected that the spinner will land on pink 20 * (1/5) = 4 times.
So, it should land on pink 4 times in 20 spins according to theoretical probability.
if it landed on pink twice what was the frequency of it landing on pink
If the spinner landed on pink twice in 20 spins, then the frequency of landing on pink is 2. This means that out of the 20 spins, the spinner landed on the pink sector 2 times.
Are the values for part (1) and part (3) the same?
Why or why not? (use complete sentences)
(part 1 was the first question part 3 was the 2nd
The values for part (1) and part (3) are not the same. Part (1) calculated the theoretical probability of landing on the pink sector, which is 1/5 or 0.2. Part (3) determined that if the spinner landed on pink twice in 20 spins, the frequency of landing on pink was 2. The theoretical probability provides an expected likelihood or chance of an event occurring, while the frequency represents the actual number of times an event occurred in a given set of trials. In this case, the theoretical probability and the frequency can differ because probability is based on expectations and assumptions, while frequency is based on actual observations or outcomes.
can u make it more simple
The values for part (1) and part (3) are not the same because part (1) calculated the expected chance of landing on pink (1 out of 5 spins), while part (3) measured the actual number of times the spinner landed on pink in a set of 20 spins (2 times). The theoretical probability is the expected likelihood of an event occurring, while the frequency is the actual number of times the event happened.
