1237.15=1237.15
There will be no negative number
for a power of ten all you need is just add a zero, example, 10 to the power of 10 just add ten zeros behind the 10 -------> 100,000,000,000
Answer:Number of squares colored red= 180-40= 140 squares
Step-by-step explanation:
Hannah has a grid of squares that has 12 rows with 15 squares in each row. This means the length of the gris is 15 squares and the breadth is 12 squares.
Area of grid = length × breadth
=15×12 = 180
She colors 5 rows of 8 squares in the middle of the grid blue. This means the part coloured blue has a length of 8 squares and breadth of 5 squares.
Area of blue colored part = 8×5 = 40
Number of squares colored red= total number of squares - number of square colored blue= 180-40= 140 squares
Answer:
a) Probability of no broken bats in a game P(X=0) = 0.3678
b) Probability of at-least broken bats in a game P(X≥2) = 0.2644
Step-by-step explanation:
we will use Poisson distribution
P(X=x) = e^(-λ) λ^ r/r!
a) Probability of no broken bats in a game P(X=0) = e^-1
= 0.3678
b) Probability of at-least two broken bats in a game
P(X≥2) = 1-([p(x=0)+P(x=1)]
= 1- (e^(-1)+e^(-1))
= 1-(0.3678+0.3678)
P(X≥2)= 1- 0.7356
P(X≥2)= 0.2644
