all of the marbles are placed in a bag, and then one is randomly selected.
a. the probability that the selected marble will have a b written on it is
a) 1/3
b) 3/5
c) 2/5
d) 3/8

b. the probability that the selected marble will be green is points.
a) 3/5
b) 5/16
c) 1/5
d) 1/3

A.

Number of marbles with 'B' written on them is [ n(A)] = 6.

Total number of marbles [ n(S)] = 15.

Thus, Probability is

P(A) = n(A) / n(S)

= 6/15 = 2/5. ⬅️

B.

Number of green marbles [ n(A)] = 5.

Total number of marbles [ n(S)] = 15.

Thus, Probability is

P(A) = n(A) / n(S)

= 5/15 = 1/3 ⬅️

hi im bob : l

step-by-step explanation:

m∠abd = m∠dbc

step-by-step explanation:

given : ab bisects ∠dbc

as we know that bisection means ab divides   ∠dbc   in two equal angles named as   ∠dba and   ∠abc

so, m∠abd = m∠dbc  

because ab bisects ∠dbc.

hence , the first statement m∠abd = m∠dbc is true.
