Don't sum up all the heads, as the question says atmost 1 head
which means that jada se jada 1 head hi aana chahiye; ya toh 0 head ya fir 1 head..not more than that(not 2 heads)..thus:--
Answer:
Total outcomes=1000
Step-by-step explanation:
Number of outcome with atmost heads=250+550=800
As, Probability=No. of oucomes favourable to event/Total number of outcomes
=>P(Atmost one head)=800/1000=4/5
Thus, The probability that the coins have atmost one head is 4/5 or 0.8.
i hope it cleared your doubt.
