To find the probability of landing on a consonant, we need to add up the frequencies of K, N, and D.
Frequency of consonants = Frequency of K + Frequency of N + Frequency of D = 120 + 105 + 135 = 360
Total frequency (sum of all outcomes) = Frequency of K + Frequency of I + Frequency of N + Frequency of D = 120 + 140 + 105 + 135 = 500
Therefore, the probability of landing on a consonant on the next spin is:
Probability of consonant = Frequency of consonants / Total frequency = 360 / 500 ≈ 0.72
Therefore, the answer is a) 0.72.
Outcomes K I N D
Frequency 120 140 105 135
A spinner is divided into 4 sections labeled as K, I, N, D. Xavier reproduced the wheel and uses a computer to simulate the outcomes of 500 spins. What is the approximate probability that the spinner will stop on a consonant on the next spin?
a 0.72
b 0.28
c 0.24
d 0.45

Bowls A and B contain a number of white and red balls. Simon and Clark repeatedly selected a ball from both bowls and recorded the results in a table. Whose results will give you a better indication about the proportion of white and red balls in each bowl? Explain your answer.
We cannot determine whose results will give a better indication about the proportion of white and red balls in each bowl without additional information about Simon and Clark's methods.
For example, if Simon and Clark both randomly select balls from the bowls and record the results, and they each perform a large number of trials, then their results may provide a good indication of the proportion of white and red balls in each bowl. However, if one or both of them use a biased method, such as selecting only from certain parts of the bowls or purposefully picking certain colors, their results may not be reliable.
Furthermore, if we know the initial number of white and red balls in each bowl, we may be able to compare Simon and Clark's results to the expected proportions based on those initial numbers to determine which person's results are more accurate.
So, without additional information, we cannot determine whose results will give a better indication about the proportion of white and red balls in each bowl.
