Answer:





Step-by-step explanation:
Given
Success
Failure
Consecutive trials until S happens
Number of trials
For every possible outcome, the last 3 must be SSS. So, we have:
The only possibility here is: 
because 3 trials implies that all outcomes must be S.

The only possibility here is:
because 4 trials implies that the first outcome must be F

The possibilities are:
because 5 trials implies that the first and the second outcomes must be FS or SF.

The possibilities are:
because 6 trials implies that the first three outcomes are: FFF, SSF and SFF
The possibilities are:
because 7 trials implies that the first three outcomes are: FFFF, FSSF and SSFF and FFSF (similar to (e))

Undefined.
Step-by-step explanation:
Comment
Let's begin by discussing why a calculator throws up and gives an error when Tan(pi/2) is entered.
Start by entering Tan(89) which is 1 degree from pi/2. The calculator is very well behaved when you do that, but look at how big Tan(89) is. 57.29. That's pretty big as these things go.
I was taught that the answer to Tan(pi/2) was infinity which I think is no longer in vogue. I think you should be answering Undefined.
Answer:
the total area of the given figure.
Step-by-step explanation:
Length of the bigger rectangle = 13 ft
Breadth of the bigger rectangle = x
Area of the bigger rectangle = A = 13 ft × x
Length of the smaller rectangle = 5ft
Breadth of the smaller rectangle = y = 6 ft
Area of the smaller rectangle = a = 5ft × 6ft
from the figure :
x + y = 14
x = 14ft - 6 ft = 8 ft
Total area of the figure = A + a

the total area of the given figure.
