Question 28
Two coins are tossed 1000 times and the outcomes are recorded as below

$\begin{matrix} N u m b e r o f h e a d s & 2 & 1 & 0 F r e q u e n c y & 200 & 550 & 250 \end{matrix}$

Based on this information, the probability for atmost one head is:

A) $\frac{1}{5}$
B) $\frac{1}{4}$
C) $\frac{4}{5}$
D) $\frac{3}{4}$

Solution

The answer is C.
The total number of coins tossed, n(S) = 1000
Number of outcomes in which atmost one head, n = 550 + 250 = 800
$∴$ Probability for atmost one head = $\frac{n (E)}{n (S)} = \frac{800}{1000} = \frac{4}{5}$
Hence, the probability for atmost one head is $\frac{4}{5}$ .

Question 28 Two coins are tossed 1000 times and the outcomes are recorded as below Number of heads210Frequency200550250 Based on this information, the probability for atmost one head is: A) 15 B) 14 C) 45 D) ​​​​​​​34​​​​​​​

The answer is C. The total number of coins tossed, n(S) = 1000 Number of outcomes in which atmost one head, n = 550 + 250 = 800 ∴ Probability for atmost one head = n(E)n(S)=8001000=45 Hence, the probability for atmost one head is 45.

The answer is C.
The total number of coins tossed, n(S) = 1000
Number of outcomes in which atmost one head, n = 550 + 250 = 800
$∴$ Probability for atmost one head = $\frac{n (E)}{n (S)} = \frac{800}{1000} = \frac{4}{5}$
Hence, the probability for atmost one head is $\frac{4}{5}$ .
