The spinner is spun once. Which sentence states how likely it is to spin a bird, cat or fish. Justify your answer. (7.DSP.5)

• Spinning a bird, cat, or fish is very unlikely since the probability is 20%

• Spinning a bird, cat, or fish is very likely since the probability is 20%

• Spinning a bird, cat, or fish is not likely since the probability is 80%

• Spinning a bird, cat, or fish is very likely since the probability is 80%
