प्रश्न
If a fair coin is tossed 10 times and the probability that it shows heads in the first four tosses and tail in last six tosses.
Advertisements
उत्तर
We want the probability that:
First 4 tosses → all Heads
Last 6 tosses → all Tails
Total number of possible outcomes
For 10 tosses:
Total outcomes=210 = 1024
There is only 1 sequence that satisfies the condition:
HHHHTTTTTT
So, favourable outcomes = 1.
`P = "Favorable outcomes"/"Total outcomes" = 1/1024`
`1/1024`
