Answer:

And we can find the individual probabilities using the probability mass function and we got:


And replacing we got:

Step-by-step explanation:
Previous concepts
The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
Let X the random variable of interest, on this case we now that:
The probability mass function for the Binomial distribution is given as:
Where (nCx) means combinatory and it's given by this formula:
Solution to the problem
For this case we want this probability:

And we can use the complement rule and we got:

And we can find the individual probabilities using the probability mass function and we got:


And replacing we got:

40%
Because, 2/5 equals 4/10. 10x10=100, so 4x10=40, so 40%.
Answer:
distribute the 2 on the left side to become 2(x+7)-->2x+14=-4x+14, add 4x to both sides to become 2x+14+4x=-4x+14+4x-->6x+14=14, subtract 14 from both sides 6x+14-14=14-14-->6x=0 and divide both sides of the equation by 6 to get x alone, 6x/6=0/6-->x=0 so x would equal 0.
Step-by-step explanation:
Answer:
the value of g is -4
Step-by-step explanation:

Our aim is to solve for g
multiply 10 inside the parenthesis

Now combine like terms
Subtract 5g from both sides


Divide both sides by -1

Answer:
The geometric figure is a Segment
Step-by-step explanation:
A and B are points since they are shown by dots and a point usually marks a location.
In Geometry a line is straight and extends in both directions infinitely.
A line segment or simply segment is the part of a line that connects two points. A segment is the shortest distance between the two points and has a length.
