M8Q8W9 Assessment

Which of the following refers to experimental probability?

• Chance of an event to happen.

• Chance of an event that must happen.

• Chance of an event not to happen.

• Chance of an event based on what happened.

Two dice are rolled 100 times and the sum 4 showed up 7 times. If the probability that the sum 4 occurred 7 times is 7/100, what probability is

illustrated?

• Expected Probability

• Subjective Probability

• Experimental Probability

• Theoretical Probability

Which of the following illustrates theoretical probability?

• The probability of drawing a face card from a standard deck of cards is 3/13.

• Sally and Tony played rock-paper-scissor 30 times, If Sally lost 14 times,

  then probability that Tony won the game is 16/30 = 8/15 = 53.3%.

• A spinner with 5 congruent sectors colored yellow, red, blue, green and white is rotated 100 times. If the arrow landed on green 20 times, then the probability of getting a color green is 20/10A spinner with 5 congruent sectors colored yellow, red, blue, green and white is rotated 100 times.
