We are given eight rooks, five of which are red and three of which are blue. A) In how many ways can the eight rooks be placed on an 8 x 8 chessboard so that no two rooks can attack one another (differentcolor rooks cannot share the same row or column).B) In how many ways can the 8 rooks be placed on a 12 x 12 chessboard so that no two rooks can attack one another?

x -

median = 1.25

range = 12-14.5

interquartile = q12-q14.5

y -

median = 1

range = 15-17

interquartile = q15-q17

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
