Answer:
The probability that exactly 2 of 5 use their smartphones in meetings or classes is 0.3442.
Step-by-step explanation:
Let <em>X</em> = number of adults who use smartphones in meetings or classes.
The probability of the random variable <em>X</em> is, P(X) = <em>p</em> = 0.42
A sample of <em>n</em> = 5 adult smartphone users are selected.
The random variable <em>X</em> follows a Binomial distribution with parameters <em>n</em> and <em>p</em>.
The probability mass function of <em>X</em> is:

Compute the value of P (X = 2) as follows:

Thus, the probability that exactly 2 of 5 use their smartphones in meetings or classes is 0.3442.
They lost 2 yards is the answer. But its difficult to tell because it could also be they gained -2 yards.

Step-by-step explanation:
the volume of a cone is
V
=
π
r
2
h
3
in this case, we can relate
h
and
r
as we know that the slope =
h
r
=

=

we can make the volume a formula in a single variable
V
=

differentiating wrt time, it follows that

The probability of an event cannot be less than 0 because 0 means it's impossible. The probability of an event cannot be more than 1 because 1 means that it's certain that it will happen. That's why the probability must be between 0 and 1.
