Answer 2

Question

❇️write the sample space S and the number of sample points n(S) Two coins are tossed?

Solution ⬇️

✍️S={HH,HT,TT,TH}={4}

✍️n(s)=4

________________________________

Extra sum

• ️if it is asked as getting atleast one head

✍️S={HH,HT,TT,TH}={4}

✍️n(s)=4

• Let A be the event of getting atleast one head

✍️A={3}

✍️n(A)=3

$= = > p(a) = \frac{n(a)}{n(s)} = \frac{3}{4}$

• ️if it is asked of getting exactly one head

✍️S={HH,HT,TH,TT}

✍️n(S)=4

• Let B be the event of getting only one head

✍️A={HT,TH}={2}

✍️n(A)=2

$= = > p(b) = \frac{p(b)}{n(s)} = \frac{2}{4} = \frac{1}{2}$

hope you appreciate this ans
