Heya!
Here is your answer:
2 ×

+10
we know that,

= 9
so,
2×9 +10
According to BODMAS (bar, Order, division, multiplication, addition, subtraction)
we multiply 2×9 = 18
then,
18+ 10
= 28
The number is 758 because there is 7 hundred blocks and 5 ten blocks and 8 one blocks which is 758
The answer would be C done this yesterday
Step-by-step explanation:
p = 0.1, q = 0.9, n = 7
a) Use complementary probability.
P(at least 1) = 1 − P(0)
P(at least 1) = 1 − (0.9)⁷
P(at least 1) = 0.522
b) Use binomial probability.
P = nCr pʳ qⁿ⁻ʳ
P(3) = ₇C₃ (0.1)³ (0.9)⁴
P(3) = 0.023
