A spinner has 8 equal sectors, of which 1 is yellow. The spinner is spun 240 times. How many times would you EXPECT it to land on yellow?
A spinner has 20 equal sectors, 2 of them purple. The spinner is spun once. Write down the probability that it lands on purple, as (a) a fraction in simplest form, (b) a decimal, and (c) a percentage.
An ordinary fair die is rolled once. Determine the probability that the roll is NOT a number greater than 4.
A spinner with 4 equal sectors, 1 of them green, is spun 100 times. It lands on green 24 times. Determine the relative frequency of landing on green, as a decimal.
A die is rolled 50 times, and a six comes up 11 times. Determine the relative frequency of rolling a six, as a decimal.
An ordinary fair die is rolled once. Determine the probability that the roll is NOT a multiple of 3.
A bag contains 9 green, 7 white and 2 yellow counters. One counter is drawn at random. Determine the probability that the counter is NOT green.
A coin is flipped 500 times and lands on heads 205 times. Determine the relative frequency of heads, as a decimal.
A bag contains 19 green and 31 orange counters (50 in total). One counter is drawn at random. Write down the probability that the counter is green, as (a) a fraction in simplest form, (b) a decimal, and (c) a percentage.
A bag contains 9 yellow counters only. One counter is drawn at random. Event: the counter is yellow. Choose the word that best describes this event: impossible, unlikely, even chance, likely, or certain.
A coin is flipped 400 times and lands on heads 228 times. Determine the relative frequency of heads, as a decimal.
A die is rolled 400 times, and a six comes up 48 times. Determine the relative frequency of rolling a six, as a decimal.
