2.5 is the mean of this distribution.
What is the distribution's mean?
- The expected value, commonly known as the mean of a statistical distribution with a continuous random variable, is calculated by integrating the product of the variable's probability as described by the distribution.
- The lowercase Greek letter mu () stands for the expected value. A probability of 50% equals zero standard deviations, and the mean is in the middle of the normal distribution.
Given: p = 0.05 and n= 50
Mean of the binomial distribution = n×p = 50 × 0.05 = 2.5
Therefore, option a is the correct answer. Other options are incorrect because these are irrelevant.

Answer: 5x+3
Let's go over this problem step by step:
First, you need to combine all the line terms.
2x + 1 + 3x + 2
Next, you get this equation:
( 2x + 3x ) + ( 1 + 2 )
2x and 3x is 5x. 1 and 2 is 3.
So your final answer is 5x+3.
Okay so, you have to think so lets say Kayla bought 30 kilograms of chicken nuggets (k), for $20 (p). You would put t=pk. Because if you change (p) and (k) you will get a different (t).
According to his calculations, b has a 3/10 chance to win
