The probability that you roll a 5 on a six-sided die is start fraction one over six end fraction . the probability that you flip

a coin that lands on heads is start fraction one over two end fraction. the probability that you roll a 5 on a six-sided die and you flip a coin that lands on heads is start fraction one over 12 end fraction. what is the probability of flipping a coin and it landing on heads, given that you rolled a 5 on a six-sided die? are these two events independent?

Let event A be the coin landing on heads and let event B be rolling a 5 on a six-sided die.
Events A and B are independent if, and only if:
P(A\cap B)=P(A)\times P(B)
It is given in the question that the above condition for independence is met.
Also A and B are independent if:
P(A|B) = P(A)
P(A) = 1/2
Therefore the probability of flipping a coin and it landing on heads, given that you rolled a 5 on a six-sided die is 1/2. The two events are independent.

Answer:

128 deg

Step-by-step explanation:

The sum of the measures of the angles of a polygon of n sides is

(n - 2)180

A trapezium has 4 sides, so the sum of the measures of the angles is

(4 - 2)180 = 2(180) = 360

<em>m<CBE + m<C + m<D + m<DEB = 360</em>

Angles ABC and CBE are a linear pair so the sum of their measures is 180 deg.

m<ABC + m<CBE = 180

115 + m<CBE = 180

m<CBE = 65

m<C = x

m<D = 90

Angles DEB and DEF are a linear pair so the sum of their measures is 180 deg.

m<DEB + m<DEF = 180

m<DEB + m<103 = 180

m<DEB = 77

<em>m<CBE + m<C + m<D + m<DEB = 360</em>

65 + x + 90 + 77 = 360

x + 232 = 360

x = 128

Answer: 128 deg

Can someone help me with this math question i really don’t know how to do it!
julia-pushkina [17]

Answer:

1260

Step-by-step explanation:

He asked 180 people and 63 said cookies so I think you have to do 63 out of each 180 people so you would do 3600 ÷ 180 = 20, 20 x 63 =1260

Not sure if this is right, hope this helps
