En una escuela intermedia de 80 estudiantes, 42 niñas y 38 niños, ¿cuál es la probabilidad de que si dos estudiantes fueran elegidos al azar, el primero sea un niño y luego una niña de forma secuencial?

the size of the resulting matrix is 1-by-3.

step-by-step explanation:

the size of the two matrices given are as follows:

no .of rows of matrix 1 = 1

no .of columns of matrix 1 = 3

no .of rows of matrix 1 = 3

no .of columns of matrix 1 = 3

to find the size of the resulting matrix without actually solving the multiplication of the matrix, this is what you do:

if resulting matrix = matrix 1 * matrix 2

no. of rows of the resulting matrix = number of rows of matrix 1

no. of columns of resulting matrix = number of columns of matrix 2

note: the order of the matrices matter!

this is a good question! i’ll do some research and what i find, i’ll contact you asap when i have something! ✊
