Abel uses a probability simulator to roll a six-sided number cube 100 times and to flip a coin 100 times. The results of the experiment are shown below: Number on the Cube Number of Times Rolled 1 12 2 18 3 30 4 22 5 10 6 8 Heads Tails 34 66 Using Abel's simulation, what is the probability of rolling a 2 on the number cube and the coin landing on tails? fraction 84 over 10,000 fraction 1,188 over 10,000 fraction 18 over 100 fraction 66 over 100

The probability of rolling a 2 is given by: \[\large P(2)=\frac{number\ of\ 2s\ rolled}{total\ rolls}\]

Not really. What is the probability of rolling a 2 (using the equation in my first post here)?
anonymous
  • anonymous
total roll is 100?
anonymous
  • anonymous
@kropot72 am not sure what
kropot72
  • kropot72
The number 2 came up 18 times in a total of 100 rolls.

@kropot72 just saw what you are talking about

18/100
kropot72
  • kropot72
Correct. The probability of tails is found from: \[\large P(tails)=\frac{number\ of\ tails}{total\ flips}\]
anonymous
  • anonymous
66/100
kropot72
  • kropot72
Correct again. Therefore as @Mertsj told you, the required probability is given by: \[\frac{18}{100}\times\frac{66}{100}=you\ can\ calculate\] Hint: Do not simplify the result of your calculation.

10000

So the result is \[\large \frac{1188}{10000}\]

yes
