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`
