If X is the number of tails in three tosses of a coin, determine the standard deviation of X.

A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
`lambda_("min")=(hc)/(eV)`
By comparing `log lambda_("min")= -logV+"log"(hc)/(e )` with `y=mx +c`
Slope m will be negative and graph will be linear. Hence, option (C ) is correct.
