To find the probability of pulling a blue marble and the coin landing tails up, we need to find the number of times Simon pulled a blue marble and the coin landed tails up, and divide it by the total number of trials.
From the table:
- Blue marbles pulled: 15
- Tails landed up: 24
The combined events where Simon pulled a blue marble and the coin landed tails up is 15 (blue marbles) * 24 (tails) = 360
Total number of trials is the sum of all events in the simulation: 15 (blue) + 19 (green) + 16 (yellow) + 26 (heads) + 24 (tails) = 100
Therefore, the probability of pulling a blue marble and the coin landing tails up is 360/100 = 36/10 = 18/5 = 3.6
This is equivalent to 360 over 100 or 36 over 10. So, the answer is 360 over 100.
Simon used a probability simulator to pull 3 colored marbles from a bag and flip a coin 50 times. The results are shown in the tables below:
Color of Marble Number of Times Rolled
Blue 15
Green 19
Yellow 16
Heads Tails
26 24
