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
Answer:
Common Difference(d) is
Step-by-step explanation:
Given sequence is :
If a sequence has a constant common difference throughout the sequence, then the sequence is called Arithmetic Progression.
Considering a sequence:
where 'd' is the common difference of the A.P.
Similarly, finding the common difference of the given sequence.
Common Difference(d) is
