we need to find the probability of bad sound cards.
we are having 1000 computers so 1000 sound card will be there.
manager found that 4 sounds are defective out of 1000 sound cards.
of defective sound cards=
we know that 1 is the total probability.out of 0.004 is the failure.
The answer is 40/6 ............
Total: 10
P = 4/10
P = 2/5
The probability is 2/5
Answer:
784 sq cm
Step-by-step explanation:
Let's find rectangular areas first.
16*24 + 10*16 (adding both areas of both rectangles)
384+160 = 544 sq cm
Now lets find the side triangles.
b*h/2 is the equation
24*10 = 240 (remove 1/2 because you have 2 triangles, 1/2*2 = 1)
240 sq cm + 544 sq cm = 784 sq cm.
