three coins are tossed simultaneously 100 times with The frequencies of different outcomes
If the three coins are simultaneously tossed again compute the probability of :
(a) 2 heads coming up.
(b) 3 heads coming up.
(c) at least one head coming up.
(d) getting more heads and tail.
Answers
Answer:
yes
Step-by-step explanation:
It is quite simple. You may easily understand it.Before finding the probability of any questions first try to find out the number of sample space. If you once got the sample space then you can easily find out whatever you want.
Now find out the sample space. Start with head and put one tail and shift it left. Similarly two or three tails.
Sample space
HHH, HHT, HTH, THH, HTT, THT, TTH, TTT
Total number of sample space is = 8
Now you have to understand that what does at least means.
It means you have to consider the value with 2 head or more.
For at least two head
HHH , HHT , HTH, THH
Total number of outcomes =4
Probablity(atleasttwohead)=(no.ofoutcomes)/(totalno.ofpossibleoutcomes)
Probablity(atleasttwohead)=4/8=1/2
