    Step-by-step explanation:

    a. The t-shirts comes in 5 sizes (Small, medium, large, extra large and extra extra large) and two colors orange and black. The total different type of shirts are 5*2=10 different type of t-shirts. Also if we make sample space of all shirts we can assess the total different type of t-shirts. sample space=S={small orange, medium orange, large orange, XL orange, XXL orange, small black, medium black, large black, XL black, XXL black}. n (S) = total different type of shirts=10.

    b. P (large orange t-shirt) = n (large orange t-shirt) / n (S) = 1/10=0.10.
