You are interested i n determining whether a particular child can discriminate the color green from blue. Therefore, you show t he child live woodenblocks. The blocks are identical except that two are green and three are blue. You randomly arrange the blocks i n a row and ask him to pick out a green block. After a b lock is picked, you replace it and randomize the order of the blocks once more. Then you again ask him to pick out a green block. This procedure is repeated until the child has made 14 selections. I f he rea lly can’t discriminate green from blue, w hat is t he probability he w ill pi ck a green block at least 11 times? cognitive
