Answer:
Congruent by SAS
Step-by-step explanation:
The three given sides of one triangle is shown to be equal to the corresponding sides of the other triangle.
This means that all threes sides of one are congruent to all corresponding sides of the other triangle.
By the Side-Side-Side Congruence Theorem, we can conclude that both triangles are congruent.
Answer:
Step-by-step explanation:
(-∞,2)
P(at least 5 rolls until 1) = P(4 rolls are not 1) = 5/6 x 5/6 x 5/6 x 5/6 = 0.4823 (4sf)
Fewer than 7 rolls to get second 1 after first takes 3 rolls means second occurs on 4th, 5th or 6th roll
The probability of each of these is 1/6, 5/6 x 1/6 and 5/6 x 5/6 x 1/6 respectively.
P(second 1 on 4th, 5th or 6th roll) = 1/6 + 5/36 + 25/216 = 91/216 = 0.4213 (4sf)
