Mathematics
1 answer:
cricket20 [7]2 years ago
6 0

Answer:

\left[\begin{array}{cc}6&18\\\end{array}\right]

Step-by-step explanation:

To find the product of the matrices: \left[\begin{array}{cc}4&2\\\end{array}\right] × \left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right]

Multiply rows of the first matrix by the columns of the second matrix.

(4 × (–2) + 2 × 7          4 × 5 + 2 × (–1))

After simplifying this, we get the product \left[\begin{array}{cc}6&18\\\end{array}\right]

Hence, \left[\begin{array}{cc}4&2\\\end{array}\right] × \left[\begin{array}{cc}-2&5\\7&-1\\\end{array}\right] = \left[\begin{array}{cc}6&18\\\end{array}\right]

Answer:

The probability of drawing the first pink ball is \frac{3}{10}.

Because you drew that first pink ball, there are two pink balls left and the total number of balls left is nine.

Hence, the probability of drawing another pink ball after drawing the first pink ball would be:

\frac{3}{10} *\frac{2}{9} =\frac{1}{15}
