Two coins are tossed in an experiment. Which of the following list is the sample space? S= {HH, HT, TH, TT}, S= {HH, TT}, S= { HT, TH, TT}, S= {HH, HT, TT}

Nico labels an x-axis with points earned and the corresponding y-axis with the number of players. He plots one against the other and obtains a bar graph called a what?

If you had no idea what the answer to this four option multiple choice was and took a wild guess, what is the probability that you are correct?

TRUE or FALSE: The standard normal distribution of a random variable is a normal distribution with mean =0 and standard deviation =1.

TRUE or FALSE: The area between 0 and a positive value z is the same as the area between 0 and -z.

TRUE or FALSE: The area that corresponds to z = 2.58 is the same as the area that corresponds to z = -2.58, which is A = 0.4951

Find the area that corresponds to z = -1.15
