Answer:
0.0139
Step-by-step explanation:
Given that in a test for extrasensory perception, the experimenter looks at cards containing either a star, circle, wave, or square. (The subject cannot see the cards.)
Probability for guessing a correct shape out of 4 shapes = 0.25
Each trial is independent of the other
Hence X no of correct guesses is binomial with n = number of cards = 20 and p = constant probability =0.25
the probability a subject correctly guesses at least 10 of the 20 shapes
=
, where F represents the cumulative probability upto 9
= 0.0139
Step-by-step explanation:
Use the above formula
-5 is the difference between the numbers..

Answer:
Miriam walks for 1.8 miles and jogs for 0.9 miles.
Step-by-step explanation:
The path for jogging is 2.7 miles.
One lap of the path, that is 2.7 miles, is completed by Miriam by jogging part and walking part.
Let the jogging part be x miles.
It is given she jogs half the distance she walks , therefore we can say that she walks for 2x miles.
So we can say that 2x + x = 2.7 miles ⇒ 3x = 2.7 miles
⇒ x = 0.9 miles.
Therefore Miriam walks for 1.8 miles and jogs for 0.9 miles.

Step-by-step explanation:
50-40%=60%
50-60%=40%
If it’s going 110mph, and the question if asking how many mph will it go for half an hour. Simply just take 110 divided by 2.
Which gives u 55
