70 years, and the standard deviation was 5.1 years. If a sample of 50 people from this region is selected, what is the probability that the mean life expectancy will be less than 71 years?
Create a program based on the sample output using while loop.
Enter a Number : 10
1*2 = 2
2*4 = 8
3*6 = 18
4*8 = 32
5*10 = 50
Let Y be the random variable representing the number of tails that occur. Find the values of the random variable Y
Combustion of an 8.23 mg sample of a compound gave 9.63 mg of carbon dioxide and 3.94 mg water. Analysis of another 5.32 mg sample of the same compound by the Carius method gave 13.49 mg of AgCl.

We’ve tried adding together integers, so how about adding characters as well? Well we really don't know how to create a variable that holds the combined characters (at least for now) so let's just print them together in 1 string instead.
Instructions:
Input two characters in one line, separated by a space.
Make the strings be printed out like it’s concatenated (or combined) by printing it without spaces in between. Refer to the sample output for your reference.
Input
A line containing two characters separated by a space.
A·B
Output
A line containing two characters.

Now this one's a tad bit tricky, but you can definitely do it!
Instructions:
Input five integers in one line, with each integer separated by a space.
Add the 1st and 2nd integers together and store the sum inside a variable.
Add the 3rd and 4th integers together and store the sum inside a variable.
Multiply the two sums and raise the product result to the power of the 5th integer.
Print out the result.
Input
A line containing five integers separated by a space.
1·2·3·4·5
Output
A line containing an integer.
