Answer

Explanation:

Step1: Calculate total number of volcanoes

$13 + 18+6=37$

Step2: Calculate probability of cinder - cone volcano

$P(\text{cinder cone})=\frac{13}{37}\approx 0.35$

Step3: Calculate probability of shield volcano

$P(\text{shield})=\frac{18}{37}\approx 0.49$

Step4: Calculate probability of stratovolcano

$P(\text{stratovolcano})=\frac{6}{37}\approx 0.16$

Answer:

Cinder cone: $\frac{13}{37}\approx 0.35$ Shield: $\frac{18}{37}\approx 0.49$ Stratovolcano: $\frac{6}{37}\approx 0.16$
