Three coins are tossed simultaneously 200 times with the following frequencies of different outcomes:
|
Outcome |
3 heads |
2 heads |
1 head |
No head |
|
Frequency |
23 |
72 |
77 |
28 |
If the three coins are simultaneously tossed again, compute the probability of 2 heads coming up.
Number of times 2 heads come up = 72
Total number of times the coins were tossed = 200
