hey could anyone please answer this fast. with steps plss. three coins are tossed simultaneously 200 times with the following frequencies od different outcomes.
number of tails :- 0 1 2 3 frequency :- 35 45 42 78
if the coins are tossed again the probability of at least two heads is...??
At least two heads is - two heads or three heads.
In other words, in line with given data, it means 1 tail or 0 tails.
If we add the frequencies of 0 tails or 1 tail, it becomes 35+45 = 80.
Then, our probability would become 80/200 = 2/5 or 0.4
