When you add 2 negatives you get a negative for example -5+-15= -20 when you add a positive to a negative it increases the number for example -20+7= -13. Hope this helps

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

= $P(X\geq 10)\\= 1-F(9)$ , where F represents the cumulative probability upto 9
