Are the triangles similar?

mestny [16]

Another way to prove triangles are similar is by SSS, side-side-side. If the measures of corresponding sides are known, then their proportionality can be calculated. If all three pairs are in proportion, then the triangles are similar.

Mumz [18]

Answer:

0.0594 = 5.94% probability of rain on November 1 and 2, but not on November 3.

Step-by-step explanation:

Rain on November 1:

0.9 of 0.6(rain on Oct 31).

0.3 of 0.4(not rain on Oct 31).

Rain on November 2:

Considering rain on November 1, 0.9 probability of rain.

Rain on November 3:

Considering rain on November 2, 0.1 probability of rain.

Find the probability of rain on November 1 and 2, but not on November 3.

Multiplicating the probabilities:

$p = (0.9*0.6+0.3*0.4)*0.9*0.1 = 0.0594$

0.0594 = 5.94% probability of rain on November 1 and 2, but not on November 3.
