Sue used a probability simulator to roll a 6-sided number cube and flip a coin 100 times. The results are shown in the tables below: Number on the Cube Number of Times Rolled 1 18 2 25 3 12 4 32 5 3 6 10 Heads Tails 56 44 81 over 100 56 over 100 1400 over 10000 1100 over 10000

    heads is 56 tails is 44

    Using Sue's simulation, what is the probability of rolling a 2 on the number cube and the coin landing heads up?

    i put 81/100 but i feel like that is wrong haha

    Ok, so the total number of times rolled is 100, correct? (18+25+12+32+3+10) = 100

    So we have \[\frac{ 25 }{ 100 }\] for the number of times 2 was rolled in a 100 rolls of dice

    Now we find the probability of dice, 56+44 = 100 (total amount flipped) We get \[\frac{ 56 }{ 100 }\] for the possibility of getting heads right

    Now all we have to do is \[\frac{ 25 }{ 100 } \times \frac{ 56 }{ 100 }\] that will give us our total probability
