Let 
be the random variable for the weight of any given can, and let 
and 
be the mean and standard deviation, respectively, for the distribution of .
You have
Recall that for any normal distribution, approximately 99.7% of it lies within three standard deviations of the mean, i.e.
. This means 0.3% must lie outside this range, 
. Because the distribution is symmetric, it follows that 
.
Also recall that for any normal distribution, about 95% of it falls within two standard deviations of the mean, so
, which means 5% falls outside, and by symmetry, 
.
Together this means
Solving for the mean and standard deviation gives
and 
.

Answer:
Step-by-step explanation:
Given : The total number of cards in a deck = 52
Number of red cards = 26
There are two types of red cards : diamond and heart.
Number of diamond cards = 13
The probability that the first card is a diamond :-
Since diamond is also a red card.
Now, the total cards left = 51
The number of red cards left = 12
The probability that the second card is a red card (without repetition) is given by :-
Now, the probability of choosing a red card for the second card drawn, if the first card, drawn without replacement, was a diamond :-
